GENERAL DESCRIPTION
The dual 14.318 MHz clock outputs allows one output for the system and one to be the input to an ICS graphics frequency generator such as the AV9194. The CPU clock offers the unique feature of smooth, glitch-free transitions from one frequency to the next, making this ideal device to use whenever slowing the CPU speed. The AV9155 makes a gradual transition between frequencies, so that it obeys the Intel cycle-to-cycle timing specification for 486 systems. The simultaneous 2X and 1X CPU clocks offer controlled skew to within 1.5ns (max) of each other. ICS offers several versions of the AV9155. The different devices are shown below: FEATURES
Compatible with 286, 386, and 486 CPUs Supports turbo modes Generates communications clock, keyboard clock, floppy disk clock, system reference clock, bus clock and CPU clock Output enable tristates outputs Up to 100 MHz at 5V or 3.3V 20-pin DIP or SOIC All loop filter components internal Skew-controlled 2X and 1...
