Description
The Si52147 is a nine port PCIe clock generator
compliant to the PCIe Gen1, Gen2 and Gen3 standards.
The Si52147 is a 48-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 Si52147 needs
a crystal or clock input of 25 MHz. The connections are
described in this document.
