Description
The Si52144 is a four port PCIe clock generator compliant with the PCIe Gen1, Gen2 and Gen3 standards. The Si52144 is a 24-pin QFN device that operates on a 3.3 V power supply and can be controlled using SMBus signals along with hardware control input pins. The differential outputs support spread spectrum and can be controlled through SSON input pin. The Si52144 needs a crystal or clock input of 25 MHz. The connections are described in this document.
