ICS844246D中文资料瑞萨数据手册PDF规格书

General Description

The ICS844246D is a Crystal-to-LVDS Clock Synthesizer/Fanout

Buffer designed for Fibre Channel frequencies and Gigabit Ethernet

applications. The output frequency can be set using the frequency

select pins and a 25MHz crystal for Ethernet frequencies, or a

26.5625MHz crystal for a Fibre Channel. The low phase noise

characteristics of the ICS844246D make it an ideal clock for these

demanding applications.
