General Description

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.

Features

• 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

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.
