Si52254 Datasheet 4/8-output Pcie Gen1/2/3/4/5 Clock Generator

Manufacturer: Skyworks Solutions

Overview: 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. For more information about PCI Express, Skyworks' complete PCIe portfolio, application notes, and design tools, including the Skyworks PCIe Clock Jitter Tool for PCI Express compliance, please visit the Skyworks PCI Express Learning Center.
