AV9107C-17

CPU Frequency Generator

General Description

The AV9107C-17 offers a tiny footprint solution for

generating two simultaneous clocks. One clock, the

REFCLK, is a fixed output frequency which is the same as

the input reference crystal (or clock). The other clock,

CLK1, can vary between 25.06 and 33.29 MHz.

The device has advanced features which include on-chip

loop filters, tristate outputs, and power-down capability. A

mini-mum of external components - two decoupling

capacitors and an optional ferrite bead - are all that are

required for jitter-free operation.

Features

• Patented on-chip Phase-Locked Loop with VCO

for clock generation

• Provides reference clock and synthesized clock

• Generates frequencies of 25 and 33 MHz

• 8-pin DIP or SOIC package

• 14.318 MHz input reference frequency

• On-chip loop filter

• Low power CMOS technology

• Single +3.3 or +5 volt power supply

Applications

Computer: The AV9107C-17 is the ideal solution for

replacing high speed oscillators and for reducing clock

speeds to save power in computers. The device provides

smooth, glitch-free frequency transitions so that the CPU

can continue to operate during slow down or speed up. The

rate of frequency change makes the AV9107C-17

compatible with all 386DX, 386SX, 486DX, 486DX2, and

486SX devices.
