Features
Compatible to Intel
CK-Titan & CK-408 Clock Synthe-
sizer/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 recov-
ery
Automatically switch to HW selected or SW pro-
grammed clock frequency when Watchdog timer times
out
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
