General Description

The AV9110 generates user specified clock frequencies using an externally generated input reference, such as 14.318 MHz or 10.00 MHz crystal connected between pins 1 and 14. Alternately, a TTL input reference clock signal can be used. The output frequency is determined by a 24-bit digital word entered through the serial port. The serial port enables the user to change the output frequency on-the-fly.

The clock outputs utilize CMOS level output buffers that operate up to 130 MHz.

Features

? Complete user programmability of output frequency through serial input data port

? On-chip Phase-Locked Loop for clock generation

? Generates accurate frequencies up to 130 MHz

? Tristate CMOS outputs

? 5 volt power supply

? Low power CMOS technology

? 14-pin DIP or 150-mil SOIC

? Very low jitter

? Wide operating range VCO

Applications

Graphics: The AV9110 generates low jitter, high speed pixel (or dot) clocks. It can be used to replace multiple expensive high speed crystal oscillators. The flexibility of this device allows it to generate nonstandard graphics clocks, allowing the user to program frequencies on-the-fly.
