SI52144-A01AGM

CLOCK GENERATOR, 100MHZ, QFN-24.

The SI52144-A01AGM is a spread-spectrum enabled PCIe Clock Generator can source four PCIe clocks. The device has four hardware output enable pins for enabling the outputs and one hardware pin to control spread spectrum on PCIe clock outputs. In addition to the hardware control pins, I?C 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.
