GENERAL DESCRIPTION

The 840051I is a Gigabit Ethernet Clock Generator and a

member of the HiPerClocksTM family of high performance

devices from ICS. The 840051I can synthesize 10 Gigabit

Ethernet, SONET, or Serial ATA reference clock fre-quencies

with the appropriate choice of crystal and output divider. The

840051I has excellent phase jitter performance and is packaged

in a small 8-pin TSSOP, making it ideal for use in systems with

limited board space.
