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.

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.
