描述

The LMK1C110x 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.

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

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

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

The LMK1C110x family operates in a 1.8-V, 2.5-V and 3.3-V environment and are characterized for operation from –40°C to 125°C.

特性
