Description

932S401 is a main clock synthesizer for CK410-generation Intel server platforms. 932S401 is driven with a 14.318MHz crystal. It generates CPU outputs up to 400MHz and PCI-Express clocks at 100 or 200 MHz. The 48 MHz USB clock is an exact 48.000 MHz clock. The 932S401 generates all clocks with less the +/- 300 ppm error.
