ESCRIPTION
The ICS843246I is a Crystal-to-3.3V LVPECL
Clock Synthesizer/Fanout Buffer designed for
HiPerClockS™
Fibre Channel and Gigabit Ethernet appli-
cations and is a member of the HiperClockS™
family of High Performance Clock Solutions
from ICS. The output frequency can be set using the fre-
quency select pins and a 25MHz crystal for Ethernet
frequencies, or a 26.5625MHz crystal for a Fibre Channel.
The low phase noise characteristics of the ICS843246I
make it an ideal clock for these demanding applications.
