Si52254/Si52258 Data Sheet 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 common 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.
