General Description

The ICS843256 is a Crystal-to-3.3V LVPECL Clock Synthesizer/Fanout Buffer designed for HiPerClockS™ 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 characteristics of the ICS843256 make it an ideal clock for these demanding applications.
