Description
The Si52147 is a spread-controlled PCIe clock generator that can source
nine PCIe clocks simultaneously. The device has six hardware output
enable control inputs for enabling the respective differential outputs on the
fly while powered on along with the hardware spread control for EMI
reduction.
