Si52258 Description

The Si52258 and Si52254 source eight and four 100 MHz PCIe differential clock outputs, respectively. All clock outputs are pliant to PCIe Gen1/2/3/4/5 mon 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.
