8/4-Output PCIe Gen 1/2/3/4/5/6 Clock Buffers

The Si53258/54 are the industry's highest performance and lowest power automotive grade PCI Express fanout buffers for PCIe Gen1/2/3/4/5/6 common clock and/or SRIS applications. The Si53258 and Si53254 source eight and four 100 MHz PCIe differential clock outputs, respectively. All clock outputs are compliant to PCIe Gen1/2/3/4/5/6 common clock and separate reference clock architecture specifications.

Hardware control pins are available for enabling and disabling the outputs, as well as input selection for devices that include dual-input functionality.
