8.3.3 Function Pins

Pins 1 and 2 on the LMK6L-Q1 serve multiple functions as defined by the OPN (refer to Section 4 for more information). Configurations include Output Enable (OE) and Stand By (ST) on pin 1, and Output Frequency Select (FSEL) on pin 2. FSEL divides the frequency defined in the OPN (or FOUT) by 2 or 4, providing 3 different frequencies from one OPN. FSEL is further described in Table 8-1 and Section 8.3.3.1. OE is Active High and ST is Active Low by default, contact TI for other options.

Pin 1 is driven internally with a 150kΩ pullup resistor. Pin 2 is driven internally with a 200kΩ pullup and 200kΩ pulldown resistors. Both pin 1 and 2 can have a external pullup or pulldown resistor between 0Ω to 10kΩ each.

Table 8-1 Function Pin Descriptions for LMK6L-Q1
ORDERABLE OPTION (7TH CHARACTER) PIN NO. PIN DESCRIPTION OUTPUT FUNCTION
E Pin 1 Output Enable (Active High) or No Connect HIGH or No Connect: Output active at specified frequency
LOW: Output disabled, high impedance; current consumption is given by IDD-OD
Pin 2 No Connect N/A
A Pin 1 Standby (Active Low) or No Connect HIGH or No Connect: Output active at specified frequency
LOW: High Impedance; standby mode; current consumption is given by standby current IDD-STBY
Pin 2 No Connect N/A
K Pin 1 Output Enable (Active High) or No Connect HIGH or No Connect: Output active at specified frequency
LOW: Output disabled, high impedance; current consumption is given by IDD-OD
Pin 2 FSEL(1) HIGH: Output active at FOUT/2
FLOATING: Output active at FOUT
LOW: Output active at FOUT/4
L Pin 1 Standby (Active Low) or No Connect HIGH or No Connect: Output active at specified frequency
LOW: High Impedance; standby mode; current consumption is given by standby current IDD-STBY
Pin 2 FSEL(1) HIGH: Output active at FOUT/2
FLOATING: Output active at FOUT
LOW: Output active at FOUT/4
(1) FOUT is the output frequency defined in the OPN (refer to Section 4).

In standby mode, all blocks are powered down to provide a maximum current consumption savings equivalent to the standby current provided in the Current Consumption Characteristics portion of Electrical Characteristics. The return time to the active output clock, or tST-EN, corresponds to the same as the initial start-up time, or tSTART_UP.
