SI53159 FANOUT BUFFER

The Si53159 is a high-performance, low additive jitter, PCIe clock buffer that can fan out nine PCIe clocks. The clock outputs are compliant to PCIe Gen 1, Gen 2, Gen 3, and Gen 4 specifications. The device has six hardware output enable control pins for enabling and disabling differential outputs. The small footprint and low power consumption makes the Si53.
