System Peripheral Clock Source
Description
The ICS650-01 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 14.31818 MHz crystal input
to produce up to eight output clocks. The device
provides clocks for PCI, SCSI, Fast Ethernet, Ethernet,
USB, and AC97. The user can select one of three USB
frequencies and also one of two AC97 audio
frequencies. The OE pin puts all outputs into a high
impedance state for board level testing. All frequencies
are generated with less than one ppm error, meeting
the demands of SCSI and Ethernet clocking.
