ICS650R-21 Description

The ICS650-21 is a low cost, low jitter, high performance clock synthesizer for system peripheral applications. Using analog/digital Phase-Locked Loop (PLL) techniques, the device accepts a parallel resonant 25 MHz crystal input to produce up to eight output clocks. The device provides clocks for PCI, SCSI, Fast Ethernet, Ethernet, USB, and AC97.
