Description
Si52111-A1/A2 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 specifications. The ultra-small
footprint (3x3 mm) and industry leading low power consumption make
Si52111-A1/A2 the ideal clock solution for consumer and embedded
applications.
