📥 Download Datasheet

General Description

The Si52143 is a spread-spectrum enabled PCIe clock generator that can source four PCIe clocks and a 25 MHz reference clock.

The device has three hardware output enable pins for enabling the outputs (on the fly while powered on), and one hardware pin to control spread spectrum on PCIe clock outputs.

In addition to the hardware control pins, I2C programmability is also available to dynamically control skew, edge rate and amplitude on the true, compliment, or both differential signals on the PCIe clock outputs.
