Motherboard Clock Generator
Description
The ICS2694 Motherboard Clock Generator is an integrated circuit using PLL and VCO technology to generate virtually all the clock signals required in a PC.
The use of the device can be generalized to satisfy the timing needs of most digital systems by reprogramming the VCO or reconfiguring the counter stages which derive the output frequencies from the VCO’s.
The primary VCO is customarily used to generate the CPU clock and is so labeled on the ICS2694.
Pre-programmed frequency sets are listed on page 6.
These choices were made to match the major microprocessor families.
CPUSEL (0-3) allow the user to select t...
