Integrated Circuit Systems, Inc. AV9155C-44 Low Cost 20-Pin Frequency Generator 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.
