描述
The 5V41235 is a PCIe Gen2/3 compliant spread spectrum capable clock generator. The device has 2 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. The 5V41235 can also supply 25 MHz, 125 MHz and 200 MHz outputs for applications such as Ethernet.
