Features

Applications

Description

The Si52142 is a spread-controlled PCIe clock generator that can source

two PCIe clocks and a 25 MHz reference clock. The device has three

hardware output enable control inputs for enabling the respective outputs

on the fly while powered on along with the hardware input for spread

spectrum and frequency control on outputs. In addition to the hardware

control pins, I2C programmability is also available to promptly achieve

optimum clock signal integrity through skew and edge rate control on true,

compliment, or both differential outputs as well as amplitude control.
