The SI52143-A01AGM is a spread-spectrum enabled PCIe Clock Generator can source four PCIe clocks and a 25MHz reference clock. The device has three hardware output enable pins for enabling the outputs (on the fly while powered on) and one hardware pin to control spread spectrum on PCIe clock outputs. In addition to the hardware control pins, I2C programmability is also available to dynamically control skew, edge rate and amplitude on the true, compliment or both differential signals on the PCIe clock outputs. This control feature enables optimal signal integrity as well as optimal EMI signature on the PCIe clock outputs. Refer to AN636 for signal integrity tuning and configurability.

• Low power, push-pull HCSL compatible differential outputs
• No termination resistors required
• Dedicated output enable hardware pins for each clock output
• Spread enable pin on differential clocks
• Four PCI-express clocks
• Signal integrity tuning
• Triangular spread spectrum profile for maximum electromagnetic interference (EMI) reduction
