PI6C557-05BLEX

The PI6C557-05B is a spread spectrum clock generator compliant to PCI Express 3.0 and Ethernet requirements. The device is used for PC or embedded systems to substantially reduce Electromagnetic Interference (EMI). The PI6C557-05B provides four differential (HCSL) or LVDS spread spectrum outputs. The PI6C557-05B is configured to select spread and clock selection. Using Pericom's 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 provides spread selection of - 0.5%, - 1.0%, - 1.5%, and no spread.
