Description
General part information
PI6C557-03AQ Series
The PI6C557-03AQ is a spread spectrum clock generator compliant to PCI Express® 2.0 and Ethernet requirements. The device is used for PC or embedded systems to substantially reduce Electro-magnetic Interference (EMI).The PI6C557-03AQ provides two differential (HCSL) or LVDS spread spectrum outputs. The PI6C557-03AQ is configured to select spread and clock selection. Using Diodes' patented Phase- Locked Loop (PLL) techniques, the device takes a 25MHz crystal input and produces two pairs of differential outputs (HCSL) at 25MHz, 100MHz, 125MHz and 200MHz clock frequencies. It also provides spread selection of -0.5%, -0.75%, and no spread.
