The LMK1C110x is a modular, high-performance, low-skew, general-purpose clock buffer family. 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.
In this reference design this clock buffer provides five times 25-MHz frequency to the five Ethernet PHYs.
