AV9155C-44 General Description

The AV9155C-44 is a low cost frequency generator designed specifically for desktop and notebook PC applications with either 3.3V or 5.0V power supply voltage. Its CPU clocks provide all necessary CPU frequencies for 286, 386 and 486 systems, including support for the latest speeds of processors. The device uses a 14.318 MHz crystal to generate the CPU and all peripheral clocks for integrated desktop motherboards.

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, glitchfree transitions from one frequency to the next, making this ideal device to use whenever slowing the CPU speed. The AV9155C-44 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.

AV9155C-44 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 1X CPU clocks
· Power-down option
