The PI6C557-05 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 Elec- tromagnetic Interference (EMI).
The PI6C557-05 provides four differential (HCSL) or LVDS spread spectrum outputs. The PI6C557-05 is configured to select spread and clock selection. Using Diodes' patented Phase- Locked Loop (PLL) techniques, the device takes a 25MHz crys- tal 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.
