7 Detailed Description

7.1 Overview

The LM98714 is a 16-bit, three-input, complete Analog Front End (AFE) for digital color copier and Multi-Function Peripheral (MFP) applications. The system block diagram of the LM98714, shown in Functional Block Diagram highlights the main features of the device. Each input has its own Input Bias and Clamping Network which are routed through a selectable Sample/Hold (S/H) or Correlated Double Sampler (CDS) amplifier. A ±9-Bit Offset DAC applies independent offset correction for each channel. A -3 to 17.9dB Programmable Gain Amplifier (PGA) applies independent gain correction for each channel. The LM98714 also provides independent Digital Black Level Correction Feedback Loops for each channel. The Black Level Correction Loop can be configured to run in Manual Mode (where the user inputs their own values of DAC offset) or in Automatic Mode where the LM98714 calculates each channel’s Offset DAC value during optical black pixels and then adjusts the Offset register accordingly. The signals are routed to a single high performance 16-bit, 45 MHz analog-to-digital converter.

7.3 Feature Description

7.3.1 Input Clock Introduction

The clock input to the LM98714 can be a differential LVDS clock on the INCLK+ and INCLK- pins or a CMOS level clock applied to the INCLK+ pin with the INCLK- pin connected to DGND. The external clock signal format is auto sensed internally. In addition to the two available level formats, the input clock can be applied at the Pixel frequency (PIXCLK) or at the ADC frequency (ADCCLK). The LM98714 can perform internal clock multiplication when a Pixel frequency clock is applied, or no multiplication when an ADC frequency clock is applied. The internal configuration registers need to be written to perform the proper setup of the input clock. Table 1 shows the available input clock configurations for each operating mode.

Table 1. Input Clock Configurations

AFE Mode	Input Clock Type	Internal Multiplier	INCLK Max Freq.	Configuration Register Settings
Mode 3	INCLK = Pixel Freq. (PIXCLK)	3x	15 MHz	PIXCLK Configuration: Main Config Reg 1, Bit[2] = 1'b1
Mode 3	INCLK = ADC Freq. (ADCCLK)	1x	45 MHz	ADCCLK Configuration: Main Config Reg 1, Bit[2] = 1'b0
Mode 2	INCLK = Pixel Freq. (PIXCLK)	2x	22.5 MHz	PIXCLK Configuration: Main Config Reg 1, Bit[2] = 1'b1
Mode 2	INCLK = ADC Freq. (ADCCLK)	1x	45 MHz	ADCCLK Configuration: Main Config Reg 1, Bit[2] = 1'b0
Mode 1	INCLK = Pixel Freq. = ADC Freq (ADCCLK = PIXCLK in Mode 1)	1x	30MHz	Main Config Reg 1, Bit[2] = 1'bx

7.3.2 Modes of Operation

The LM98714 can be configured to operate in several different operating modes. The following sections are a brief introduction to these modes of operation. A more rigorous explanation of the operating modes is contained in the Modes of Operation section. including input sampling diagrams for each mode as well as a description of the operating conditions.

7.3.2.1 Mode 3 - Three Channel Input/Synchronous Pixel Sampling

OS_B, OS_G, and OS_R inputs are sampled synchronously at a pixel rate. The sampled signals are processed with each channel’s offset and gain adjusted independently via the control registers. The order in which pixels are processed from the input to the ADC is fully programmable and is synchronized by the SH pulse. In this mode, the maximum channel speed is 15MSPS per channel with the ADC running at 45MSPS yielding a three color throughput of 45MSPS.

7.3.2.2 Mode 2 - Two Channel Input/Synchronous Pixel Sampling

Mode 2 is useful for CCD sensors with a Black and White mode with Even and Odd outputs. In its default configuration, Mode 2 samples the Even output via the OS_B channel input, and the Odd output via the OS_G channel input. Sampling of the Even and Odd pixels is performed synchronously at a maximum sample rate of 22.5MSPS per input with the ADC running at 45MSPS.

7.3.2.3 Mode 1a - One Channel Input/One, Two, Three, Four, or Five Color Sequential Line Sampling

In Mode 1a, all pixels are processed through a single input (OS_R, OS_G, or OS_B) chosen through the control register setup. This mode is useful in applications where only one input channel is used. The selected input is programmable through the control register. If more than one color is being sent to the input, the user can configure the OS_R channel to utilize up to five offset and gain coefficients for up to five different lines of color pixels. The SH pulse at the beginning of each line sequences the DAC and PGA coefficients as configured in the control registers. In this mode, the maximum channel speed is 30MSPS per channel with the ADC running at 30MSPS.

7.3.2.4 Mode 1b - One Channel Input Per Line/Sequential Line (Input) Sampling/Three Channel Processing

In Mode 1b the OS_R, OS_G, and OS_B inputs are sampled one input per line with the input selection being sequenced to the next color by an SH pulse. This mode is useful with sensors that output whole lines of pixels of a single color. The order in which the inputs are sampled is fully programmable. Sequencing from one channel to the next is triggered by the SH pulse. The first SH pulse after this mode is set (or reset) sets up the first programmed input for gain and offset and initiates sampling through that input alone. The next SH pulse switches the active input to the second channel indicated by the configuration registers. This sequencing with SH pulses continues to the third input and then continuously loops through the inputs. In this mode, the maximum channel speed is 30MSPS per channel with the ADC running at 30MSPS.

7.3.3 Input Bias and Clamping

Figure 2. Input Bias and Clamping Diagram

The inputs to the LM98714 are typically AC coupled through a film capacitor and can be sampled in either Sample and Hold Mode (S/H Mode) or Correlated Double Sampling Mode (CDS Mode). In either mode, the DC bias point for the LM98714 side of the AC coupling capacitor is set using the circuit of Figure 2 which can be configured to operate in a variety of different modes.

A typical CCD waveform is shown in Figure 3. Also shown in Figure 3 is an internal signal “SAMPLE” which can be used to “gate” the CLPIN signal so that it only occurs during the “signal” portion of the CCD pixel waveform.

LM98714 Typical_CCD_Waveform_LM98714_Clamp_Signal.gif

Figure 3. Typical CCD Waveform and LM98714 Input Clamp Signal (CLPIN)

LM98714 Sample_and_Hold_Mode_Simplified_Input_Diagram.gif

Figure 4. Sample and Hold Mode Simplified Input Diagram

Proper DC biasing of the CCD waveform in Sample and Hold mode is critical for realizing optimal operating conditions. In Sample/Hold mode, the Signal Level of the CCD waveform is compared to the DC voltage on the VCLP pin. In order to fully utilize the range of the input circuitry, it is desirable to cause the Black Level signal voltage to be as close to the VCLP voltage as possible, resulting in a near zero scale output for Black Level pixels.

In Sample/Hold Mode, the DC bias point of the input pin is typically set by actuating the input clamp switch (see Figure 2) during optical black pixels which connects the input pins to the VCLP pin DC voltage. The signal controlling this switch is an auto-generated pulse, CLPIN. CLPIN is generated with a programmable pixel delay with respect to SH and a programmable pixel width. These parameters are available through the serial interface control registers.

Actuating the input clamp will force the average value of the CCD waveform to be centered around the VCLP DC voltage. During Optical Black Pixels, the CCD output has roughly three components. The first component of the pixel is a “Reset Noise” peak followed by the Reset (or Pedestal) Level voltage, then finally the Black Level voltage signal. Taking the average of these signal components will result in a final “clamped” DC bias point that is close to the Black Level signal voltage.

To provide a more precise DC bias point (i.e. a voltage closer to the Black Level voltage), the CLPIN pulse can be “gated” by the internally generated SAMPLE clock. This resulting CLPIN_GATED signal is the logical “AND” of the SAMPLE and CLPIN signals as shown in Figure 3. By using the CLPIN_GATED signal, the higher Reset Noise peak will not be included in the clamping period and only the average of the Reset Level and Black Level components of the CCD waveform will be centered around VCLP.

LM98714 Equivalent_Input_Switched_Capacities.gif

Figure 5. Equivalent Input Switched Capacitance S/H Mode

In Sample and Hold Mode, the impedance of the analog input pins is dominated by the switched capacitance of the CDS/Sample and Hold amplifier. The amplifier switched capacitance, shown as C_S in Figure 4, and internal parasitic capacitances can be estimated by a single capacitor switched between the analog input and the VCLP reference pin for Sample and Hold mode. During each pixel cycle, the modeled capacitor, C_SH, is charged to the OS_X-VCLP voltage then discharged. The average input current at the OS_X pin can be calculated knowing the input signal amplitude and the frequency of the pixel. If the application requires AC coupling of the CCD output to the LM98714 analog inputs, the Sample and Hold Mode input bias current may degrade the DC bias point of the coupling capacitor. To overcome this, Input Source Follower Buffers are available to isolate the larger Sample and Hold Mode input bias currents from the analog input pin (as discussed in the following section). As shown in Figure 6, the input bias current is much lower for CDS mode, eliminating the need for the source follower buffers.

7.3.3.1 CDS Mode

LM98714 CDS_Mode_Simplified_Input_Diagram.gif

Figure 6. CDS Mode Simplified Input Diagram

Correlated Double Sampling mode does not require as precise a DC bias point as does Sample and Hold mode. This is due mainly to the nature of CDS itself, that is, the Video Signal voltage is referenced to the Reset Level voltage instead of the static DC VCLP voltage. The common mode voltage of these two points on the CCD waveform have little bearing on the resulting differential result. However, the DC bias point does need to be established to ensure the CCD waveform’s common mode voltage is within rated operating ranges.

The CDS mode biasing can be performed in the same way as described in the Sample/Hold Mode Biasing section, or, an alternative method is available which precludes the need for a CLPIN pulse. Internal resistor dividers can be switched in across the OS_R, OS_G, and/or OS_B inputs to provide the DC bias voltage.

Figure 7. CDS Mode Input Bias Current

Unlike in Sample and Hold Mode, the input bias current in CDS Mode is relatively small. Due to the architecture of CDS switching, the average charge loss or gain on the input node is ideally zero over the duration of a pixel. This results in a much lower input bias current, whose main source is parasitic impedances and leakage currents. As a result of the lower input bias current in CDS Mode, maintaining the DC Bias point the input node over the length of a line will require a much smaller AC input coupling capacitor.

7.3.3.2 Input Source Follower Buffers

The OS_R, OS_G, OS_B inputs each have an optional Source Follower Buffer which can be selected with Main Configuration Register 1, Bit[7]. These source followers provide a much higher impedance seen at the inputs. In some configurations, such as Sample and Hold Mode with AC coupled inputs, the DC bias point of the input nodes must remain as constant as possible over the entire length of the line to ensure a uniform comparison to reference level (VCLP in this case). The Source Followers effectively isolate the AC input coupling capacitor from the switched capacitor network internal to the LM98714’s Sample and Hold/CDS Amplifier. This results in a greatly reduced charge loss or gain on the AC Input coupling capacitor over the length of a line, thereby preserving its DC bias point.

The Source Followers should only be used in the 1.2 V input range (i.e. Main Configuration Register 2, Bit[4] = 1, CDS Gain = 2x). Using the Source Followers in the 2.4 V (i.e. Main Configuration Register 2, Bit[4] = 0, CDS Gain = 1x). input range will result in a loss of performance (mainly linearity performance at the high and low ends of the input range).

7.3.3.3 VCLP DAC

The VCLP pin provides the reference level for incoming signals in Sample and Hold Mode. The pin’s voltage can be set by one of three sources by writing to the VCLP Configuration Register on register page 0. By default, the VCLP pin voltage is established by an internal resistor divider which sets the voltage to VA/2. The resistor ladder can be disconnected and the pin driven externally by the application.

The most flexible method of setting the VCLP voltage is using the internal VCLP DAC buffer. The DAC is connected by setting the VCLP Configuration register Bit[5:4] to 2b’01. The DAC has a four bit “offset binary” format which is summarized in Table 2. The DAC output has an approximate swing of ±1.2 V.

Table 2. VCLP DAC Format

VCLP Configuration [3:0]	Typical VCLP Output
0	-Full Scale
0111	Mid Scale - LSB
1000	Mid Scale
1001	Mid Scale + 1 LSB
1111	+Full Scale

7.3.4 Coarse Pixel Phase Alignment

Precise placement of the CCD video signal sampling point is a critical aspect in any typical imaging application. Many factors such as logic gate propagation delays and signal skew increase the difficulty in properly aligning the CCD pixel output signals with the AFE input sampling points. The LM98714 provides two powerful features to aid the system level designer in properly sampling the CCD video signal under a large range of conditions. The first feature, discussed in this section, is the Coarse Pixel Phase Alignment block. As the name implies, this block provides a very coarse range of timing adjustment to align the phase of the CCD Pixel output with the phase of the LM98714 sample circuit. The second feature, discussed on the Internal Sample Timing section, is the block which is designed for fine tuning of the sampling points within the selected Coarse Pixel Alignment Phase. A small portion of a typical imaging application is shown in Figure 8.

Figure 8. Typical AFE/CCD Interface

As shown in the diagram, the LM98714 provides the timing signals to drive the CCD using external logic gates to drive the high capacitance CCD clock pins. The pixels are shifted out of the CCD, through the emitter follower buffers and received by the LM98714 inputs for processing.

In an ideal application, depicted in Figure 9, the Pixel output signal would be in phase with the timing signals that drove the CCD. The LM98714 input sampling clocks (CLAMP and SAMPLE) are adjustable within a pixel period. By default, the pixel period (or pixel “phase”) is defined to be in line with the input clock. As shown in the ideal case in Figure 9, CLAMP and SAMPLE can be properly adjusted to their ideal positions within the pixel phase, shown below at the stable region near the end of the pedestal and data phases.

Figure 9. Clock Alignment in an Ideal Application

In a real system however, propagation delays exist in all stages of the signal chain. These propagation delays will lead to a shift in the CCD Pixel outputs with respect to the LM98714 input clock. The phase shift of the CCD Pixel output, demonstrated in Figure 10, can lead to significant sample timing issues if not properly corrected.

LM98714 CCD_Output_Phase_Shift_Real_App.gif

Figure 10. CCD Output Phase Shift in a Real Application

In the default mode, the LM98714 sampling is performed during a clock period whose phase is aligned with the input clock (ignoring any clock tree skew for the moment). The actual sampling clocks are adjustable within the clock period, as shown in Figure 10 (shown for CDS mode in the diagram) and further described in the Internal Sample Timing section. As shown in the diagram, the delay of the CCD Pixel output is shifted far enough that the fine CLAMP and SAMPLE clocks cannot be placed in a stable portion of the waveform. To remedy this situation, the LM98714’s Coarse Pixel Phase Alignment feature allows the designer to shift the entire phase of the analog front end with respect to the input clock. This allows the designer to choose one of four sampling phases which best matches the delay in the external circuitry. Once the “Coarse Pixel Phase” has been chosen, the designer can then fine tune the sampling clocks using the fine adjustment (see Internal Sample Timing).

The four available Coarse Pixel Phases (PIXPHASE0 - PIXPHASE3) are depicted in Figure 11 (Mode 3), Figure 12 (Mode 2) and Figure 13 (Mode 1). Also shown in the diagrams are the external input clock (INCLK) and a typical CCD output delayed from the input clock.

7.3.5 Internal Sample Timing

A typical CCD input signal is depicted in Figure 14 and Figure 15. Also shown are the internally generated SAMPLE and CLAMP pulses. These signals provide the sampling points of the input signal (OS_X). The timing of SAMPLE and CLAMP is derived from an internal system clock (SYSCLK).

The pixel’s reference level input (depicted as V_REF) is captured by the falling edge of the CLAMP pulse. In Sample/Hold Mode the V_REF input is a sample of the VCLP DC voltage. In CDS Mode the CLAMP pulse samples the pedestal Level of the CCD output waveform.

The pixel’s signal level input (depicted as V_SIG) is captured by the SAMPLE pulse. In either Sample/Hold or CDS Mode, the V_SIG input is the signal level of the CCD output waveform.

The LM98714 provides fine adjustment of the CLAMP and SAMPLE pulse placement within the pixel period. This allows the user to program the optimum location of the CLAMP and SAMPLE falling edges. In CDS mode, both CLAMP and SAMPLE are independently adjustable for each channel in use. In Sample/Hold mode, CLAMP is coincident with SAMPLE by default, but is also independently adjustable. The available fine tuning locations for CLAMP and SAMPLE are shown in Figure 16 through Figure 21 for each sampling mode (CDS or S/H) and channel mode (3, 2, or 1 Channel).

7.3.6 Automatic Black Level Correction Loop

CCD signal processors require a reference level for the proper handling of input signals; this reference level is commonly referred to as the black level. The LM98714 provides an Automatic Black Level Correction Loop as shown in Figure 22. The timing for this function is shown in Figure 23. The loop can be disabled and the Black Level Offset DAC registers programmed manually if desired.

Figure 22. Black Level Correction Loop

The loop is intended to be used prior to scanning the page or during the first several lines at the beginning of a scan. The loop calibrates the channel offset such that the ADC outputs the desired code for Optical Black Pixels. In automatic mode, the pixels used to calibrate the offset should be Optical Black pixels represented by the internal “BLKCLP” pulse in Figure 23.

7.3.6.1 Black Level Offset DAC

The offset level registers store the DAC value required to meet the respective channel’s black level output. While using the Auto Black Level Correction Loop, the DAC registers are re-written as required every line the loop is enabled.

7.3.6.2 Black Level Clamp (BLKCLP)

The BLKCLP pulse can be synchronized by either the falling edge of the SH pulse or the CLPIN pulse (both shown in Figure 23). The automatic BLKCLP pulse will begin “n” number of pixel periods after the falling edge of the reference pulse where “n” is the Auto Black Level Clamp Position register. The reference point is programmed by the BLKCLP Mode Select Bits[1:0] within the Black Level Clamp Control register. The BLKCLP pulse should not be programmed coincident to the CLPIN pulse (if the CLPIN pulse is being used).

LM98714 Black_Level_Correction_Timing.gif

Figure 23. Black Level Correction Timing

7.3.6.3 Pixel Averaging

In order to obtain a snapshot of the current value for black (for comparison with the desired level of black) the ADC output is sampled upon activation of BLKCLP. Since a single optical black pixel is unlikely to be an accurate representation of the black level, a number of adjacent pixels are averaged. The number of pixels sampled is programmable by the Pixel Averaging Bit[5:4] within the Black Level Clamp Control register. The ability to select the number of pixels to be averaged (4, 8, 16, or 32 per line) provides greater flexibility allowing the LM98714 to be used with different CCDs having differing number of black pixels.

7.3.6.4 Target Black Level

The Target Black Level registers define a 10-bit word that specifies an ADC output (on the 12 bit level) corresponding to the desired optical black output code (ignoring the four LSBs of the 16 Bit ADC output). In other words, one Target Black Level LSB corresponds to sixteen ADC LSBs. Assertion of the BLKCLP signal activates the digital black clamp loop and the black level is steered toward the value stored in the output black level register. The digital black clamp loop is only limited in it’s range by the offset DAC’s range.

Once the correct number of pixels have been averaged, the value is subtracted from the Target Black Level and an error value is produced.

7.3.6.5 Offset Integration

Each time the BLKCLP signal is activated, the average ADC output of several black pixels is compared to the Target Black Level producing an error value. This error value is not directly added (or subtracted) to the Black Level Offset register, rather, the value applied is a programmable fraction of this error. This has the effect of slowing down the offset convergence resulting in a calculation for offset that is less susceptible to noise. The scaling factor is stored in the Offset integration Bits[3:2] of the Black Level Clamp Control register. The scaling values are divided-by-8, 16, 32, or 64. Divide-by-8 provides the quickest convergence of the loop (for use when the number of lines available for calibration is limited) and Divide-by-64 the longest (for use when using an large number of lines to converge).

7.3.6.6 Line Averaging

The Auto Black level Correction Loop can be run for 15 lines, 31 lines, 63 lines, or infinite (every line). The Line Averaging Bits[7:6] found in the lack Level Clamp Control register set the number of lines that the loop will run after the Start of Scan. The recommended use of the Auto Black Level Correction Loop is in a calibration period prior to moving the sensor down the page or during the first several lines of the page. By experimenting with the Line Averaging and Offset Integration bits with no sensor illumination (black pixels), the proper settings for the Auto Black Level Correction Loop are determined when the ADC output converges to the Target Black Level value. If the loop converges with the 15, 31, or 63 line setting, the loop can remain enabled. The loop does not update the Black Level Offset DAC once the number of lines since “Start of Scan” has passed. If the loop requires more than 63 lines to converge (i.e. requires Line Averaging = infinite), it is recommended to disable the loop after convergence has been reached. In the “infinite” setting, the loop will continuously update the Black Level Offset registers as long as the loop is enabled throughout the entire scan.

7.3.7 Internal Timing Generation

A flexible internal timing generator is included to provide clocking signals to CCD and CIS sensors. A block diagram of the CCD Timing Generator is shown in Figure 24.

Figure 24. CCD Timing Generator Block Diagram

Examples of the various operating modes and settings are shown following. The detailed pixel timing is somewhat dependent on the operating modes of the AFE circuitry regarding the number of adjustment points for the on and off points of the different timing outputs.

NOTE

In addition to the timing adjustments shown, the polarity of all sensor clock signals can be adjusted by register control.

7.3.7.1 Pix Signal Generator OR/NOR Modes

As shown in Figure 24, the PIX signal generators outputs can be used in their normal form and sent to the LM98714 output pins, or, they can be sent through an additional layer of OR and NOR logic to provide a number of clocking variations. The OR and NOR combinations of multiple PIX signals can be useful for such modes as pixel lumping, or other modes where more complicated phi clocks are required.

The OR and NOR functions are chosen through the PIX OR/NOR Control 1 and PIX OR/NOR Control 2 registers on Page 4 of the serial interface register map. When all of the OR/NOR control bits are 0 (default) the PIX signals are sent directly from the pix signal generators to the output pins configured by the Output Mapping Control registers (register Page 3). When an OR/NOR control bit is set to 1, the OR or NOR product of multiple pix signal generators is routed to the output pin described in the register details.

7.3.7.2 SH2 and SH3 Generation

In some sensors, there is a requirement for up to three “SH” type signals. The LM98714 CCD Timing Generator can be configured to produce optional SH signals as shown in Figure 38, these SH signals (SH2 and SH3) toggle every other line and are coincident with the original SH pulse.

Figure 38. SH2 and SH3 Generation

The “Start Scan (BOS)” request bit is used to begin the proper sequence of CCD Timing outputs at the beginning of a scan. The first line of pixels are being processed by the CCD during the first integration period (after the first SH). The BOS signal (internal to the LM98714) occurs at the second SH to signal when the first line of pixels are actually shifting out of the CCD and in to the AFE. The SH2 pulse is synchronized with the BOS signal and continues to toggle on an every other line basis. The SH3 signal occurs on opposite lines from SH2.

The SH2 and SH3 signals are available in place of the Lamp IR1 and Lamp IR2 outputs respectively. The routing of SH2 and SH3 is depicted in Figure 24. The use of SH2 and SH3 is selected by the SH2/SH3 Control register (0x0F) on Page 4 of the register map.

Figure 39. Sensor Control Outputs

Table 3 shows a number of example mappings of the sensor timing signals to the sensor control CLKn outputs. Several typical timings are shown here, but any timing generator signal can be mapped to any of the CLKn outputs, providing maximum flexibility.

Table 3. Sensor Timing Mappings Examples

CLK9	PIX5(PHI3)	LAMPIR2	MODE	LAMPIR2	MODE	CB[4]
CLKOUT/CLK10		(MODE)		PIX5(PHI3)		CLKOUT

These examples can be used for any customer need, but typical applications would be as follows:

In Examples A, B and C, only 10 sensor control outputs are used. This is to allow the CLKOUT/CLK10 pin to be used as a timing reference for the image output data when the outputs are in CMOS mode.

Example A: Used with most CCD or CIS sensors, including new sensors with 3 PHI clock inputs. Will support up to 3 color LED lamps. Supports CCD sensors with switchable resolution through the MODE control output.

Example B: Used in applications where up to 2 additional IR lamps are used in addition to the R, G, B lamps. No resolution MODE output is available.

Example C: Used where no CP pulse is needed, but 5 lamp outputs are needed as well as a MODE sensor resolution control pin.

In Examples D and E, the CLK10 output is also used. These modes are not available when the image data outputs are operating in CMOS mode.

Example D: Provides both PHI3 output and 5 LED lamp outputs. Does not provide MODE output for resolution control.

Example E: Provides 5 LED lamp outputs, and the MODE output for sensor resolution control.

7.3.8 CCD Timing Generator Master/Slave Modes

The internal CCD Timing generator is capable of operating in Master Mode or in Slave Mode. The Master/Slave operation is configured with the SH Mode Register (Register 0x00 on Page 2). In either Master or Slave Mode, control bit data can be sent to the output of the LM98714 to indicate when each new scan is starting as well as pixel information such as color, type (active, black, dummy, etc.), and the beginning of each line.

7.3.8.1 Master Timing Generator Mode

In Master Timing Mode, the LM98714 controls the entire CCD Timing Generator based on a Start Scan Bit (Main Configuration Register 2, Bit[0] is the “Start Scan” or “BOS/Beginning of Scan” bit). The Start Scan bit is set by the user to request a new scan. This bit is a self clearing register bit written to the serial interface. When received, the LM98714 controls where and when each new line of the scan begins and ends based on the CCD Timing Generator register settings. The scan is enabled as long as the Active/Standby bit is low. The period of the line (integration time) is controlled by the SH Width setting (SH Pulse Width Register) and the Line End setting (Line End MSB and Line End LSB registers).

7.3.8.2 Slave Timing Generator Mode

In Slave Timing Mode, the LM98714 CCD Timing Generator is controlled by the external SH_R pin. Each new line of a scan is initiated by an SH_R pulse. The period of the line (integration time) is mainly controlled by the period of the incoming SH_R signal.

7.3.9.3 LVDS Control Bit Coding

The 5 control bits included in the LVDS data stream are coded as follows:

The "active" and "black" pixel tags are programmable tags that the LM98714 provides in order to identify how many pixels have been processed since the falling edge of SH.

Which pixels are given "active" and "black" CB tags is controlled by Page 4, registers 0x08 through 0x0D (Optical Black Pixels Start, Optical Black Pixels End, Start of Valid Pixels, and End of Valid Pixels).

The LM98714 counts the number of pixel periods after the falling edge of SH: If the number of pixel periods after the falling edge of SH is between "optical black pixels start" and "optical black pixels end" the CB bits will indicate that the pixel is a black pixel. If the number of pixel periods after the falling edge of SH is between "start of valid pixels" and "end of valid pixels" the CB bits will indicate that the pixel is an active pixel.

7.3.9.5 LVDS Test Modes

The LVDS test modes present several different data patterns to the input of the LVDS serializer block. All 21 bits are used and there is no control bit coding present. The SH signal resets the LVDS test pattern and the pattern will resume only after SH is deasserted. If no SH signal is sent, the pattern continues indefinitely.

7.3.9.5.1 Test Mode 1 - Worst Case Transitions

This test mode provides an LVDS output with the maximum possible transitions. This mode is useful for system EMI evaluations, and for ATE timing tests.

The effective data values are an alternating pattern between 21’b101010101010101010101 (0x155555) and 21’b010101010101010101010 (0x0AAAAA). This test pattern resets to 0x155555 after the SH signal.

Figure 48. LVDS Test Pattern

7.3.9.5.2 Test Mode 2 - Ramp

This mode provides LVDS data that progresses from 0x00000 to the full scale output 0x1FFFFF incrementing by 1 per LVDS Clock. When the LVDS ramp test pattern is selected, the ramp begins immediately and counts from zero to the full scale value, and then repeats.

7.3.9.5.3 Test Mode 3 - Fixed Output Data

This mode allows a fixed data value to be output. The value is set via. Upcounter Register 1, 2 and 3. The 21 bit value taken from these registers is repetitively sent out over the LVDS link. This is useful for system debugging of the LVDS link and receiver circuitry.

7.4.1 Mode 3 - Three Channel Input/Synchronous Pixel Sampling

In Mode 3, the OS_R, OS_G, and OS_B input channels are sampled synchronously. The sampled input signals are then processed in parallel through their respective channels with each channel offset and gain adjusted by their respective control registers. The signals are then routed through a 3-1 MUX to the ADC. The order in which pixels are processed through the MUX to the ADC is programmable (OS_R-OS_G-OS_B, or OS_B-OS_G-OS_R) and is synchronized by the SH pulse.

7.4.2 Mode 2 - Two Channel Input/Synchronous Pixel Sampling

Mode 2 is useful for CCD sensors with a Black and White line with Even and Odd pixels. In its default configuration, Mode 2 samples Even sensor pixels via the Blue Channel Input, and Odd sensor pixels via the Green Channel Input. The selection of Even/Odd inputs can be changed through the serial interface registers. Sampling of the Even and Odd inputs is performed synchronously.

7.4.4 Mode 1b - One Channel Color Input Per Line/Sequential Line (Input) Sampling/Three Channel Processing

In Mode 1b, the OS_R, OS_G, and OS_B inputs are sampled sequentially and processed through their respective channels. This mode allows an entire line of Red, Green, or Blue Pixels to be sampled before sequencing to the next input. This mode is useful with sensors that output whole lines of pixels of a single color. The order in which the channels are sampled is fully programmable. Actual switching from channel to channel is triggered by an SH pulse. The first SH pulse after this mode is set (or reset) sets up the first programmed channel for gain and offset and initiates sampling through that channel alone. The next SH pulse switches the active channel to the second channel indicated by the configuration registers. This sequencing with SH pulses continues to the third channel and then continuously loops through the channels.

7.5 Programming

7.5.1 Serial Interface

A serial interface is used to write and read the configuration registers. The interface is a three wire interface using SCLK, SEN, and SDIO connections. The main input clock (INCLK) to the LM98714 must be active during all Serial Interface commands.

7.5.1.1 Writing To The Serial Registers

To write to the serial registers, the timing diagram shown in Figure 57 must be met. First, SEN is toggled low. The LM98714 assumes control of the SDIO pin during the first eight clocks of the command. During this period, data is clocked out of the device at the rising edge of SCLK. The eight bit value clocked out is the contents of the previously addressed register, regardless if the previous command was a read or a write. At the rising edge of ninth clock, the LM98714 releases control of the SDIO pin. At the falling edge of the ninth clock period, the master should assume control of the SDIO pin and begin issuing the new command. SDIO is clocked into the LM98714 at the rising edge of SCLK. The remaining bits are composed of the “write” command bit (a zero), two device address bits (zeros for the LM98714), five bit register address to be written, and the eight bit register value to be written. When SEN toggles high, the register is written to, and the LM98714 now functions with this new data.

Figure 57. Serial Write

7.5.1.2 Reading The Serial Registers

To read to the serial registers, the timing diagram shown in Figure 58 must be met. First, SEN is toggled low. The LM98714 assumes control of the SDIO pin during the first eight clocks of the command. During this period, data is clocked out of the device at the rising edge of SCLK. The eight bit value clocked out is the contents of the previously addressed register, regardless if the previous command was a read or a write. At the rising edge of ninth clock, the LM98714 releases control of the SDIO pin. At the falling edge of the ninth clock period, the master should assume control of the SDIO pin and begin issuing the new command. SDIO is clocked into the LM98714 at the rising edge of SCLK. The remaining bits are composed of the “read” command bit (a one), two device address bits (zeros for the LM98714), five bit register address to be read, and the eight bit “don’t care” bits. When SEN toggles high, the register is not written to, but its contents are staged to be outputted at the beginning of the next command.

7.6 Register Maps

7.6.1 Configuration Registers

The LM98714 operation is very flexible to support a wide variety of sensors and system designs. This flexibility is controlled through configuration registers which are first summarized, then described in full in the following tables. Because the serial interface only allows 5 address bits, a register paging system is used to support the larger number of required registers.

A page register is present at the highest address (1Fh or 11111b). The power on default setting of the page register is 00. Writing other values to this register allows the other pages to be accessed. The page register is mirrored, and is accessible at the highest address on each page.

Figure 60 shows the proper sequence of operation for the LM98714.
