Description
Si52111-B3/B4 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 and Gen 2 specifications. The
ultra-small footprint (3x3 mm) and industry leading low power
consumption make Si52111-B3/B4 the ideal clock solution for consumer
and embedded applications.
