SI53156 FANOUT BUFFER

The Si53156 is a spread spectrum tolerant PCIe clock buffer that can source six PCIe clocks simultaneously. The device has six hardware output enable control inputs for enabling the respective differential outputs on the fly. The device also features output enable control through I2C communication. I2C programmability is also available to dynamically contro.
