The 557-05A is a spread-spectrum clock generator that supports PCI-Express requirements. It is used in PC or embedded systems to substantially reduce electro-magnetic interference (EMI). The device provides four differential HCSL or LVDS high-frequency outputs with spread spectrum capability. The output frequency and spread type are selectable using external pins.
