GENERAL DESCRIPTION

The ICS84324 is a Crystal-to-3.3V LVPECL Frequency Synthesizer with Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. Output frequency can be programmed using frequency select pins. The low phase noise characteristics of the ICS84324 make it an ideal clock source for Fibre Channel 1 and Gigabit Ethernet applications.
