Description

The ICS84327 is a Crystal-to-3.3V LVPECL Clock Synthesizer/Fanout Buffer designed for SONET, 10 Gigabit Fibre Channel and 10 Giga-bit 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 19.44MHz crystal for SONET frequencies, or a 25MHz crystal for 10 Gigabit Ethernet fre- quencies, or a 25.5MHz crystal for a 10 Gigabit Fibre Chan- nel. The low phase noise characteristics of the ICS84327 make it an ideal clock for these demanding applications.
