Si52212/Si52208/Si52204/Si52202 Data Sheet 12/8/4/2-Output PCI-Express Gen 1/2/3/4/5 and SRIS Clock Generator The Si52212/08/04/02 are the industry's highest performance and lowest power PCI Express clock generator family for 1.5–1.8 V PCIe Gen 1/2/3/4/5 and SRIS applications. The Si52212, Si52208, and Si52204 can source twelve, eight, and four 100 MHz PCIe differential clock outputs, respectively, plus one 25 MHz LVCMOS reference clock output. The Si52202 can source two 100 MHz PCIe clock outputs only. All differential clock outputs are compliant to PCIe Gen1/2/3/4/5 common clock and separate reference clock architectures specifications. The Si52212/08/04/02 feature individual hardware control pins for enabling and disabling each output, spread spectrum enable/disable for EMI reduction, and frequency select to select 100, 133, or 200 MHz differential output frequencies. These features can also be controlled via I2C. The small footprint and low power consumption make this family of ...
