Description
The Si53154 is a spread spectrum tolerant PCIe clock buffer that can source four PCIe clocks simultaneously. The device has four 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 control skew, edge rate and amplitude on the true, compliment, or both differential signals on the clock outputs.
