ICS843256I
FEMTOCLOCKS CRYSTAL-TO-3.3V LVPECL
FREQUENCY SYNTHESIZER W/INTEGRATED FANOUT BUFFER
PRELIMINARY
GENERAL DESCRIPTION
The ICS843256I is a Crystal-to-3.3V LVPECL
Clock Synthesizer/Fanout Buffer designed for
Fibre Channel and Gigabit Ethernet applications
and is a member of the HiperClockS family of
High Performance Clock Solutions from ICS. The
output frequency can be set using the frequency select
pins and a 25MHz crystal for Ethernet frequencies, or a
19.44MHz crystal for SONET. The low phase noise charac-
teristics of the ICS843256I make it an ideal clock for these
demanding applications.
