ICS557-01 Overview
The ICS557-01 is a clock chip designed for use in PCI-Express Cards as a clock source. It provides a pair of differential outputs at 100 MHz in a small 8-pin SOIC package. Using IDT’s patented Phase-Locked Loop (PLL) techniques, the device takes a 25 MHz crystal input and produces HCSL (Host Clock Signal Level) differential outputs at 100 MHz clock frequency.
