PCIE GEN 2/3 & QPI CLOCK FOR ROMLEY-BASED SERVERS
DATASHEET
932SQ420D
General Description
The 932SQ420D is a main clock synthesizer for
Romley-generation Intel based server platforms. The
932SQ420D is driven with a 25 MHz crystal for maximum
performance. It generates CPU outputs of 100 or 133.33
MHz.
