8.3.3 Function Pins

Pin 1 on the LMK6C and pin 1 or pin 2 on the LMK6P, LMK6D, and LMK6H are the function pins which have multiple functions based on the orderable part number. The function can be used as Output Enable (OE), Stand By (ST) or No Connect (NC). Options for both Active High and Active Low are available for OE and ST. Contact TI for Active Low options. Table 8-1 lists the functions of pin 1 and pin 2 for differential output 6-pin packages and Table 8-2 lists the functions of pin 1 for single-ended outputs.

Table 8-1 Function Pin Descriptions for 6-Pin Packages (LMK6D, LMK6H, LMK6P)
ORDERABLE OPTION PIN DESCRIPTION OUTPUT FUNCTION OTHER FUNCTIONAL PIN CONFIGURATION
E (Pin 1) Output Enable (Active High / NC) HIGH or No Connect: Output active at Specified Frequency
LOW: Output disabled, high impedance; current consumption is given by IDD-PD		 Pin 2 can be left floating or grounded
F (Pin 2) Output Enable (Active High / NC) HIGH or No Connect: Output active at Specified Frequency
LOW: Output disabled, high impedance; current consumption is given by IDD-PD		 Pin 1 can be left floating or grounded
A (Pin 1) Standby (Active Low) LOW: High Impedance; standby mode; current consumption is given by standby current IDD-STBY
HIGH or No Connect: Output active at Specified Frequency 		Pin 2 can be left open or grounded
B (Pin 2) Standby (Active Low) LOW: High Impedance; standby mode; current consumption is given by standby current IDD-STBY
HIGH or No Connect: Output active at Specified Frequency 		Pin 1 can be left open or grounded
Table 8-2 Function Pin Descriptions for 4-Pin Packages (LMK6C)
ORDERABLE OPTIONPIN DESCRIPTIONOUTPUT FUNCTION
E (Pin 1)Output Enable (Active High / NC)HIGH or No Connect: Output active at Specified Frequency
LOW: Output disabled, high impedance; current consumption is given by IDD-PD
A (Pin 1)Standby (Active Low)LOW : High Impedance; standby mode; current consumption is given by standby current IDD-STBY
HIGH or No Connect : Output active at Specified Frequency

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 the Electrical Characteristics table. The return to the output clock active time corresponds to same as the initial start-up time.

The Function Pin is driven internally with resistance greater than 100kΩ.
