SI52112-B4 PCI-EXPRESS GEN 2 DUAL OUTPUT CLOCK GENERATOR

Si52112-B3/B4 is a high-performance, PCIe clock generator that can source two PCIe clocks from a 25 MHz crystal or clock input. The clock outputs are compliant to PCIe Gen 1 and Gen 2 specifications. The ultrasmall footprint (3x3 mm) and industry leading low power consumption make Si52112-B3/B4 the ideal clock solution for consumer and embedded applications..
