Skyworks Solutions Inc. Si53212/Si53208/Si53204 PCIe Clock Buffers

Skyworks Solutions Inc. Si53212/Si53208/Si53204 PCIe Clock Buffers are high-performance, low-additive jitter, low-power PCIe clock fanout buffers. The devices can source 12, 8, or 4 100MHz PCIe clock outputs. All differential clock outputs comply with PCIe Gen1/2/3/4 common clock and separate reference clock specifications.

The buffers are spread spectrum tolerant of passing through a spread input clock, with each device having an individual hardware output enable control pin. This allows for enabling and disabling each differential output. The device can also support input frequencies from 10MHz to 200MHz. All the devices are packaged in small QFN packages with a small footprint and low power consumption. These PCIe clock fanout buffers are ideal for industrial and consumer applications. The Skyworks PCIe Clock Jitter Tool makes measuring PCIe clock jitter quick and easy.
