ICS84326AMT Datasheet PDF - Integrated Circuit Systems

GENERAL DESCRIPTION
The ICS84326 is a Crystal-to-3.3V LVPECL Clock Synthesizer/Fanout Buffer designed for Serial Attached SCSI applications and is a member of the HiperClockS family of High Performance Clock Solutions from ICS. Using a 25MHz crystal, the 6 LVPECL outputs can be set for either 75MHz or 150MHz using the frequency select pins. The low jitter/low phase noise characteristics make it an ideal clock source for use in Serial Attached SCSI applications or for other applications which require a 75MHz or 150MHz reference clock.
