SI52143 Datasheet (Silicon Laboratories)

SI52143, CLOCK GENERATOR

The Si52143 is a spread-spectrum enabled PCIe clock generator that can source four PCIe clocks and a 25 MHz reference clock.

The device has three hardware output enable pins for enabling the outputs (on the fly while powered on), and one hardware pin to control spread spectrum on PCIe clock outputs
