Description

Si52111-B5/B6 is a high-performance, PCIe clock generator that can

source one PCIe clock output from a 25 MHz crystal or clock input. The

clock output is compliant to PCIe Gen 1, Gen 2, Gen 3, Gen 3 SRNS and

Gen 4 common clock specifications. The ultra-small footprint (3x3 mm)

and industry leading low power consumption make Si52111-B5/B6 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
