General Description
The ICS844246D is a Crystal-to-LVDS Clock Synthesizer/Fanout
Buffer designed for Fibre Channel frequencies and Gigabit Ethernet
applications. The output frequency can be set using the frequency
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 ICS844246D make it an ideal clock for these
demanding applications.
