ICS2694 Datasheet (Integrated Circuit Systems)

ICS2694, Motherboard Clock Generator

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 count

ICS2694 Features

* Low cost - eliminates multiple oscillators and Count Down Logic Primary VCO has 16 Mask Programmable frequencies (normally CPU clock) Secondary VCO has 1 Mask Programmable frequency (usually 96 MHz) Pre-program
