SI52146 Overview
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. Internal 100 kohm pull-up.
