The PI6C557-03A is a spread spectrum clock generator compli- ant 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 PI6C557-03A provides two differential (HCSL) or LVDS spread spectrum outputs. The PI6C557-03A is configured to se- lect 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.
- Phase jitter - 2.1ps RMS (typ)
