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.
