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.
