PCI-EXPRESS GEN1 CLOCK SOURCE
Description
The ICS557-03 is a spread spectrum clock generator that
supports PCI-Express Gen 1 and Ethernet requirements.
The device is used for PC or embedded systems to
substantially reduce electromagnetic interference (EMI).
The device provides two differential (HCSL) spread
spectrum outputs. The spread type and amount are
configured via select pin. Using IDT’s patented
Phase-Locked Loop (PLL) techniques, the device takes a
25 MHz crystal input and produces two pairs of differential
outputs at 25 MHz, 100 MHz, 125 MHz or 200 MHz clock
frequencies for HCSL, and 25 MHz or 100 MHz for LVDS.
