The PI6C557-05Q 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 PI6C557-05Q provides four differential (HCSL) or LVDS spread spectrum outputs. The PI6C557-05Q 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 four pairs of differential outputs (HCSL) at 100MHz and 200MHz clock frequencies. It also pro- vides spread selection of -0.5%, -1.0%, -1.5%, and no spread.
