SNAS826 April 2022 LMK6C
The function pin is identified as pin 1 on the LMK6C and pin 1 or pin 2, depending on the grade of the device, for the LMK6P and LMK6D. In addition to output enable, the function pin is also capable of providing a chip disable / standby feature. In this mode, all blocks will be powered down to provide a maximum current consumption savings for a non-operation mode, meaning the output clock is not available. The return to the output clock active time corresponds to the initial start-up time.
The function pin can also be designed to be active high or active low. This allows for compatibility and drop in replacement with hardware that may have terminated to ground. Contact your TI representative to discuss options not listed on Figure 5-1 and Figure 5-2.
