PI6C557-01BQ数据手册集成电路（IC）的应用特定时钟/定时规格书PDF

描述 Description

The PI6C557-01BQ is a spread spectrum clock generator compliant to PCI Express® 3.0 and Ethernet requirements.  The device is used for Automotive systems. The PI6C557-01BQ provides one differential (HCSL) or LVDS spread spectrum output. Using Diodes' patented Phase-Locked Loop (PLL) techniques, the device takes a 25MHz crystal input and produces one pair of differential outputs (HCSL) at 100MHz. It also provides spread selection of -0.5% and no spread.
