CLG52147 可替换 Si52147

The CLG52147 is a high-performance, PCIe clock generator that can source nine PCIe clocks from a 25 MHz crystal or clock input.
The clock outputs are compliant to PCIe Gen 1, Gen 2, Gen 3, Gen 3/4 SRNS and Gen 5 common clock specifications. The device
has six hardware output enable control pins for enabling and disabling differential outputs. A spread spectrum control pin for EMI
reduction is also available. The small footprint and low power consumption makes the CLG52147 the ideal clock solution for
consumer and embedded applications.
