Overview
Integrated Circuit Systems, Inc.
AV9107C CPU Frequency Generator The AV9107C 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 2 and 120 MHz, with up to 16 selectable preprogrammed frequencies stored in internal ROM (frequency range depends on design option).
The device has advanced features which include on-chip loop filters, tristate outputs, and power-down capability.
A minimum of external components - two decoupling capacitors and an optional ferrite bead - are all that are required for jitter-free operation.
Standard versions for computer motherboard applications are the AV9107C-03, and AV9107C-05.
Custom masked versions, with customized frequencies and features, are available in 6-8 weeks for a small NRE.
General Description Features • • • • • • • • • Patented on-chip Phase-Locked Loop with VCO for clock generation Provides reference clock and synthesized clock Generates frequencies from 2 to 120 MHz (depending on option), operates to 80 MHz for VDD 3.
3V±10% 8-pin DIP or SOIC package or 14-pin DIP or SOIC package 2 to 32 MHz input reference frequency (depending on option) On-chip loop filter Up to 16 frequencies stored internally Low power CMOS technology Single +3.
3 or +5 volt power supply Applications Graphics: The AV9107C is the easiest to use, lowest cost, and smallest footprint frequency generator for graphics applications.
It can generate up to 16 different frequencies, including all frequencies necessary for VGA standards.
It should be used in place of the AV9105/6 when the reference clock is also needed.
Computer: The AV9107C is the ideal solution for replacing high speed oscillators and for reducing clock speeds to save power in computers.
The device provides smooth, glitchfree frequency transitions so that the CPU can continue to operate during slow down or speed up.
