Features

Applications

Description

The Si52146 is a spread-controlled PCIe clock generator that can source

six PCIe clocks simultaneously. The device has six hardware inputs for

enabling the respective outputs on the fly while powered on along with the

spread control hardware pin to enable Spread for EMI reduction.
