Product Overview

The SI52142-A01AGM is a spread-spectrum enabled PCIe Clock Generator can source two PCIe clocks and a 25MHz reference clock. The device has three hardware output enable pins for enabling the respective outputs and two hardware pins to control spread spectrum and frequency 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 and configurability.
  • Low power, push-pull HCSL compatible differential outputs
  • No termination resistors required
  • Dedicated output enable hardware pins for each clock output
  • Dedicated hardware pins for spread spectrum and frequency control on differential outputs
  • Up to two PCI-Express clocks
  • Signal integrity tuning
  • Triangular spread spectrum profile for maximum electromagnetic interference (EMI) reduction
