ICS84427中文资料ICST数据手册PDF规格书

GENERAL DESCRIPTION

The ICS84427 is a Crystal-to-LVDS Frequency Synthesizer/Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The output frequency can be programmed using the frequency select pins. The low phase noise characteristics of the ICS84427 make it an ideal clock source for 10 Gigabit Ethernet, 10 Gigabit Fibre Channel, OC3 and OC12 applications.
