ICS932S421B is a main clock synthesizer for CK410B-generation Intel server platforms. ICS932S421B is driven with a
14.318MHz crystal. It generates CPU outputs up to 400MHz and PCI-Express clocks at 100. The 48 MHz USB clock is an exact
48.000 MHz clock. The ICS932S421B generates all other clocks with less the +/- 100 ppm error.
