9EX21801A中文资料18 Output PCIe G2/QPI Differential Buffer With 2:1 Input MUX数据手册Renesas规格书

描述 Description

The 9EX21801 provides 18 output clocks for PCIe Gen2 (100MHz) or QPI (133MHz) applications. The 9EX21801 has 4 selectable SMBus addresses, and dedicated CKPWRGD/PD# and VDDA pins for easy board design. A differential CPU clock from a CK410B+ main clock generator, such as the 932S421, drives the 9EX21801. In fanout mode, the 9EX21801 provides outputs up to 400MHz.
