7 Detailed Description

7.1 Overview

The DS100KR800 is a low-power media compensation, 8-channel repeater optimized for 10G–KR. The DS100KR800 compensates for lossy FR-4 printed-circuit-board backplanes and balanced cables. The DS100KR800 operates in 3 modes: Pin control mode (ENSMB = 0), SMBus slave mode (ENSMB = 1) and SMBus master mode (ENSMB = float) to load register information from external EEPROM; refer to SMBUS master mode for additional information.

7.3 Feature Description

7.3.1 4-Level Input Configuration Guidelines

The 4-level input pins use a resistor divider to help set the four valid control levels and provide a wider range of control settings when ENSMB = 0. There is an internal 30-kΩ pullup and a 60-kΩ pulldown connected to the package pin. These resistors, together with the external resistor connection, combine to achieve the desired voltage level. By using the 1-kΩ pulldown, 20-kΩ pulldown, no connect, and 1-kΩ pullup, the optimal voltage levels for each of the four input states are achieved as shown in Table 1.

Table 1. 4–Level Control Pin Settings

LEVEL SETTING RESULTING PIN VOLTAGE
3.3-V MODE 2.5-V MODE
0 Tie 1 kΩ to GND 0.1 V 0.08 V
R Tie 20 kΩ to GND 1/3 x VIN 1/3 x VDD
F Float (leave pin open) 2/3 x VIN 2/3 x VDD
1 Tie 1 kΩ to VIN or VDD VIN – 0.05 V VDD – 0.04 V

The typical 4-level input thresholds are as follows:

  • Internal Threshold between 0 and R = 0.2 × VIN or VDD
  • Internal Threshold between R and F = 0.5 × VIN or VDD
  • Internal Threshold between F and 1 = 0.8 × VIN or VDD

In order to minimize the start-up current associated with the integrated 2.5-V regulator, the 1-kΩ pullup and pulldown resistors are recommended. If several four level inputs require the same setting, it is possible to combine two or more 1-kΩ resistors into a single lower value resistor. As an example, combining two inputs with a single 500-Ω resistor is a valid way to save board space.

7.4 Device Functional Modes

7.4.1 Pin Control Mode

When in pin mode (ENSMB = 0) , the repeater is configurable with external pins. Equalization and de-emphasis can be selected through pin for each side independently. When de-emphasis is asserted VOD is automatically adjusted per the Table 3. The receiver electrical idle detect threshold is also adjustable through the SD_TH pin.

7.4.2 SMBUS Mode

When in SMBus mode (ENSMB = 1), the VOD (output amplitude), equalization, de-emphasis, and termination disable features are all programmable on a individual lane basis, instead of grouped by A or B as in the pin mode case. Upon assertion of ENSMB the MODE, EQx and DEMx functions revert to register control immediately. The EQx and DEMx pins are converted to AD0-AD3 SMBus address inputs. The other external control pins remain active unless their respective registers are written to and the appropriate override bit is set, in which case they are ignored until ENSMB is driven low (pin mode). On power-up and when ENSMB is driven low all registers are reset to their default state. If RESET is asserted while ENSMB is high, the registers retain their current state.

Equalization settings accessible through the pin controls were chosen to meet the needs of most applications. If additional fine tuning or adjustment is needed, additional equalization settings can be accessed through the SMBus registers. Each input has a total of 256 possible equalization settings. The tables show the 16 setting when the device is in pin mode. When using SMBus mode, the equalization, VOD and de-Emphasis levels are set by registers.

The input control pins have been enhanced to have 4 different levels and provide a wider range of control settings when ENSMB=0.

7.5 Programming

7.5.1 SMBUS Master Mode

The DS100KR800 devices support reading directly from an external EEPROM device by implementing SMBus Master mode. When using the SMBus master mode, the DS100KR800 will read directly from specific location in the external EEPROM. When designing a system for using the external EEPROM, the user needs to follow these specific guidelines.

  • Set ENSMB = Float — enable the SMBUS master mode.
  • The external EEPROM device address byte must be 0xA0'h and capable of 1-MHz operation at 2.5-V and 3.3-V supply. The maximum allowed size is 8 kbits (1024 bytes).
  • Set the AD[3:0] inputs for SMBus address byte. When the AD[3:0] = 0000'b, the device address byte is B0'h.

When tying multiple DS100KR800 devices to the SDA and SCL bus, use these guidelines to configure the devices.

  • Use SMBus AD[3:0] address bits so that each device can loaded it's configuration from the EEPROM. Example below is for 4 device

    • U1: AD[3:0] = 0000 = 0xB0'h,

    U2: AD[3:0] = 0001 = 0xB2'h,

    U3: AD[3:0] = 0010 = 0xB4'h,

    U4: AD[3:0] = 0011 = 0xB6'h

  • Use a pullup resistor on SDA and SCL; value = 2 kΩ
  • Daisy-chain READEN# (pin 26) and ALL_DONE# (pin 27) from one device to the next device in the sequence so that they do not compete for the EEPROM at the same time.
    1. Tie READEN# of the 1st device in the chain (U1) to GND
    2. Tie ALL_DONE# of U1 to READEN# of U2
    3. Tie ALL_DONE# of U2 to READEN# of U3
    4. Tie ALL_DONE# of U3 to READEN# of U4
    5. Optional: Tie ALL_DONE# output of U4 to a LED to show the devices have been loaded successfully

Below is an example of a 2 kbits (256 × 8-bit) EEPROM in hex format for the DS100KR800 device. The first 3 bytes of the EEPROM always contain a header common and necessary to control initialization of all devices connected to the I2C bus. CRC enable flag to enable/disable CRC checking. If CRC checking is disabled, a fixed pattern (8’hA5) is written or read instead of the CRC byte from the CRC location, to simplify the control. There is a MAP bit to flag the presence of an address map that specifies the configuration data start in the EEPROM. If the MAP bit is not present the configuration data start address is derived from the DS100KR800 address and the configuration data size. A bit to indicate an EEPROM size > 256 bytes is necessary to properly address the EEPROM. There are 37 bytes of data size for each DS100KR800 device.

NOTE

The maximum EEPROM size supported is 8 kbits (1024 x 8 bits). For more information in regards to EEPROM programming and the hex format, see SNLA228.

7.6 Register Maps

7.6.1 System Management Bus (SMBus) and Configuration Registers

The System Management Bus interface is compatible to SMBus 2.0 physical layer specification. ENSMB = 1 kΩ to VDD to enable SMBus slave mode and allow access to the configuration registers.

The DS100KR800 has the AD[3:0] inputs in SMBus mode. These pins are the user set SMBUS slave address inputs. The AD[3:0] pins have internal pulldown. When left floating or pulled low the AD[3:0] = 0000'b, the device default address byte is B0'h. Based on the SMBus 2.0 specification, the DS100KR800 has a 7-bit slave address. The LSB is set to 0'b (for a WRITE). The device supports up to 16 address byte, which can be set with the AD[3:0] inputs. Below are the 16 addresses.

The SDA, SCL pins are 3.3-V tolerant, but are not 5-V tolerant. External pullup resistor is required on the SDA. The resistor value can be from 1 kΩ to 5 kΩ depending on the voltage, loading and speed. The SCL may also require an external pullup resistor and it depends on the Host that drives the bus.

7.6.1.1 Transfer of Data Through the SMBus

During normal operation the data on SDA must be stable during the time when SCL is High.

There are three unique states for the SMBus:

START: A High-to-Low transition on SDA while SCL is High indicates a message START condition.

STOP: A Low-to-High transition on SDA while SCL is High indicates a message STOP condition.

IDLE: If SCL and SDA are both High for a time exceeding tBUF from the last detected STOP condition or if they are High for a total exceeding the maximum specification for tHIGH then the bus will transfer to the IDLE state.

7.6.1.2 SMBus Transactions

The device supports WRITE and READ transactions. See Table 6 for register address, type (Read/Write, Read Only), default value and function information.

7.6.1.3 Writing a Register

To write a register, the following protocol is used (see SMBus 2.0 specification).

  1. The Host drives a START condition, the 7-bit SMBus address, and a 0 indicating a WRITE.
  2. The Device (Slave) drives the ACK bit (0).
  3. The Host drives the 8-bit Register Address.
  4. The Device drives an ACK bit (0).
  5. The Host drive the 8-bit data byte.
  6. The Device drives an ACK bit (0).
  7. The Host drives a STOP condition.

The WRITE transaction is completed, the bus goes IDLE and communication with other SMBus devices may now occur.

7.6.1.4 Reading a Register

To read a register, the following protocol is used (see SMBus 2.0 specification).

  1. The Host drives a START condition, the 7-bit SMBus address, and a 0 indicating a WRITE.
  2. The Device (Slave) drives the ACK bit (0).
  3. The Host drives the 8-bit Register Address.
  4. The Device drives an ACK bit (0).
  5. The Host drives a START condition.
  6. The Host drives the 7-bit SMBus Address, and a 1 indicating a READ.
  7. The Device drives an ACK bit 0.
  8. The Device drives the 8-bit data value (register contents).
  9. The Host drives a NACK bit 1 indicating end of the READ transfer.
  10. The Host drives a STOP condition.

The READ transaction is completed, the bus goes IDLE and communication with other SMBus devices may now occur.

See Table 6 for more information.
