AV9110
Integrated
Circuit
Systems, Inc.
Serially Programmable Frequency Generator
General Description
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
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.

Low power CMOS technology
14-pin DIP or 150-mil SOIC
Very low jitter
The clock outputs utilize CMOS level output buffers that
operate up to 130 MHz.
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.
