COO (Country of Origin):

The Si522xx is the industry's highest performance and lowest power PCI Express clock generator family for 1.5–1.8 V PCIe Gen1/2/3/4 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 common clock and separate reference clock architectures specifications.
