Description

The PI6C557-03 is a spread spectrum clock generator supporting PCI Express and Ethernet requirements. The device is used for PC or embedded systems to substantially reduce Electromagnetic Interference (EMI).

The PI6C557-03 provides two differential (HCSL) spread spectrum outputs. The PI6C557-03 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 ±0.25%, -0.5%, -0.75%, and no spread.
