Description

The 5V41066 is a PCIe Gen2 compliant spread-spectrum-capable clock generator. The device has 4 differential HCSL outputs and can be used in communication or embedded systems to substantially reduce electro-magnetic interference (EMI). The spread amount and output frequency are selectable via select pins.
