SILICON LABS SI53208-A02AGMR

The Si53212, Si53208, and Si53204 are the highest performance, low additive jitter, low power PCIe clock fanout buffer family that can source 12, 8, or 4 clock outputs. All differential clock outputs are compliant to PCIe Gen1/2/3/4/5 common 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.
