ICS844031BG-01 REV. A MAY 1, 2008
GENERAL DESCRIPTION
The ICS844031-01 is an Ethernet Clock Generator
and a member of the HiPerClocksTM family of high
performance devices from IDT. The ICS844031-01
uses an 18pF parallel resonant crystal over the
range of 19.6MHz - 27.2MHz. For Ether net
applications, a 25MHz crystal is used to generate 312.5MHz.
The ICS844031-01 has excellent <1ps phase jitter performance,
over the 1.875MHz - 20MHz integration range. The ICS844031-
01 is packaged in a small 8-pin TSSOP, making it ideal for use
in systems with limited board space.
