Description

The Si52146 is a high-performance, PCIe clock generator that can source six

PCIe clocks from a 25 MHz crystal or clock input. The clock outputs are

compliant to PCIe Gen 1, Gen 2, Gen 3, Gen 3 SRNS and Gen 4 common

clock specifications. The device has six output enable control pins for

enabling and disabling differential outputs. A spread spectrum control pin for

EMI reduction is also available. The small footprint and low power

consumption makes the Si52146 the ideal clock solution for consumer and

embedded applications. Measuring PCIe clock jitter is quick and easy with the

Silicon Labs PCIe Clock Jitter Tool. Download it for free at www.silabs.com/
