4/8-Output PCIe Gen1/2/3/4/5 Clock Generator
The Si52258/54 are the industry's highest performance and lowest power automotive
grade PCI Express clock generators for PCIe Gen1/2/3/4/5 common clock and/or SRIS
applications. The Si52258 and Si52254 source eight and four 100 MHz PCIe differential
clock outputs, respectively. All clock outputs are compliant to PCIe Gen1/2/3/4/5 com-
mon clock and separate reference clock architecture specifications.
Hardware control pins are available for enabling and disabling the outputs, as well as
spread spectrum enable/disable for EMI reduction.
