3 Description

The LMK1C110x-Q1 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, 1:4, 1:6 and 1:8 are available.

All family members share the same high performing characteristics such as low additive jitter, low skew, and wide operating temperature range.

The LMK1C110x-Q1 supports a synchronous output enable control (1G) which switches the outputs into a low state when 1G is low. 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.

The LMK1C110x-Q1 family are available in an Automotive Grade 1 (–40°C to 125°C) and AEC-Q100 qualified.
