OPTi Notebook Frequency Generator
General Description
Features
The AV9154A-60 is a low cost frequency generator designed
for general purpose PC and disk drive applications. Its CPU
clocks provide all necessary frequencies for 286, 386 and
486 systems, including support for the latest speeds of
processors. The standard devices use a 14.318 MHz crystal to
generate the CPU and peripheral clocks for integrated desktop
and notebook motherboards.

•
Compatible with 286, 386, and 486 CPUs
Up to 66.6 MHz (-60) CPU clocks
All loop filter components internal
3.3V and 5V operation
16-pin 150-mil SOIC
Power-down control of CPU clock
The AV9154A-60 is specifically designed for use with OPTi
core logic chip sets.
Applications
Computer Motherboards: The AV9154A-60 replaces crystals
and oscillators, saving board space, component cost, part
count and inventory costs. It produces switchable CPU clock
and up to four fixed clocks to drive floppy disk,
communications, super I/O, bus and/or keyboard devices. The
small package and 3.3V operation is perfect for handheld
computers.
The AV9154A-60 can operate at 5.0V±10% or 3.3V±10%,
but the CPU frequencies are limited (see the asterisks on the
selection tables on page three) during 3.3V operation. The
parts have two power-down pins. One shuts off the CPU clock
to a low state when the power-down pin is taken high, and the
other turns off the 14.318 MHz output in the same manner.
