CPU Frequency Generator
General Description
Features
•
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.
Patented on-chip Phase-Locked Loop with VCO

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
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.
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.
