Features
C
ompatible to Intel
CK-Titan and CK-408 Clock
Synthesizer/driver specifications
System frequency synthesizer for Intel Brookdale 845
and Brookdale
–
G Pentium
4 chipsets
Programmable clock output frequency with less than
1-MHz increment
Integrated fail-safe Watchdog timer for system
recovery
Automatically switch to hardware-selected or software-
programmed clock frequency when w timer time-out
Fixed 3V66 and PCI output frequency mode.
Capable of generating system RESET after a Watchdog
timer time-out occurs or a change in output frequency
via SMBus interface
Support SMBus byte read/write and block read/ write
operations to simplify system BIOS development
Vendor ID and Revision ID support
Programmable drive strength support
Programmable output skew support
Power management control inputs
Available in 48-pin SSOP
