All differential clock outputs are pliant to PCIe Gen 1 through Gen 6 mon clock and separate reference clock specifications. This family of buffers is spread spectrum tolerant to pass through a spread input clock. Each device has an individual hardware output enable control pin for enabling and disabling each differential output. The device can also support input frequencies from 10 MHz to 200 MHz. All the devices are packaged in small QFN packages. The small footprint and low-power  consumption make this family of PCIe clock fanout buffers ideal for industrial and consumer applications. To confirm PCI-Express pliance, the Skyworks PCIe Clock Jitter Tool makes measuring PCIe clock jitter quick and easy.
