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 www.silabs.com/pcie-learningcenter.
