FEMTOCLOCKS CRYSTAL-TO-

LVCMOS/LVTTL CLOCK GENERATOR

The ICS840001 is a Fibre Channel Clock Generator
and a member of the HiPerClocksTM family of high

HiPerClockS performance devices from IDT. The ICS840001 uses
a 26.5625MHz crystal to synthesize either
106.25MHz or 212.5MHz, using the FREQ_SEL pin.

The ICS840001 has excellent phase jitter performance, over the
637kHz 10MHz integration range. The ICS840001 is packaged
in a small 8-pin TSSOP, making it ideal for use in systems with
limited board space.
