Description

REF

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. This control feature enables optimal signal integrity as

well as optimal EMI signature on the PCIe clock outputs. Refer to AN636 for

signal integrity tuning and configurability. Measuring PCIe clock jitter is quick and

easy with the Silicon Labs PCIe Clock Jitter Tool. Download it for free at
