Si52212 Description

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 pliant to PCIe  Gen1/2/3/4/5 mon clock and separate reference clock architectures specifications.
