FEMTOCLOCKS™ CRYSTAL-TO-3.3V LVPECL FREQUENCY

SYNTHESIZER W/INTEGRATED FANOUT BUFFER

ICS843246I

IDT™ / ICS™ 3.3V LVPECL FREQUENCY SYNTHESIZER

ICS843246BGI REV. A AUGUST 2, 2007

GENERAL DESCRIPTION

The ICS843246I 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 IDT. 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 ICS843246I make it an ideal clock for these demanding

applications.
