SI52147-A01AGMR

时钟发生器及支持产品 9-output PCIe Gen 1/2/3 clock generator

PCI-EXPRESS GEN 1, GEN 2, & GEN 3 NINE OUTPUT  CLOCK GENERATOR

Description SI52147-A01AGMR

The Si52147 is a high-performance, PCIe clock generator that can source nine 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 hardware 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 Si52147 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.
