Description
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 Pericom's 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.
