ICS932S801AFLF Datasheet, PDF (3/20 Pages) List of Unclassifed Manufacturers – K8 Clock Chip for Serverworks GC-HT 2-Way Servers

ICS932S801
General Description
The ICS932S801 is a main clock synthesizer chip that, when paired with ICS9DB108, provides all clocks required by
Serverworks GC-HT-based servers.
An SMBus interface allows full control of the device.
