ESCRIPTION
The ICS843011C is a Fibre Channel Clock
Generator and a member of the HiPerClocks
TM
HiPerClockS™
family of high performance devices from ICS.
The ICS843011C uses a 26.5625MHz crystal to
synthesize 106.25MHz or a 25MHz crystal to
synthesize 100MHz. The ICS843011C has excellent <1ps
phase jitter performance, over the 637kHz – 10MHz
integration range. The ICS843011C is packaged in a small
8-pin TSSOP, making it ideal for use in systems with limit-
ed board space.
