The LMK1C110xA is a modular, high-performance, low-skew, general-purpose clock buffer family from Texas Instruments. The entire family is designed with a modular approach in mind. Five different fan-out variations, 1:2, 1:3, 1:4, 1:6 and 1:8 are available.

All of the devices within this family are pin-compatible to each other and backwards compatible to the CDCLVC110x family for easy handling.

The LMK1C110xA supports a asynchronous output enable control (1G) which switches the outputs into a low state when 1G is low. Asynchronous enable and disable is helpful for 1PPS applications and DC inputs operations. These devices have a fail-safe input that prevents oscillation at the outputs in the absence of an input signal and allows for input signals before VDD is supplied.
