General Description Features

AV9110

Block Diagram

Serially Programmable Frequency Generator

9110 Rev F 5/30/00

• 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 V CO

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.

ICS reserves the right to make changes in the device data identified in this
publication without further notice. ICS advises its customers to obtain the latest
version of all device data to verify that any information being relied upon by the
customer is current and accurate.

Pin Descriptions

Pin Configuration

14 Pin Dip, SOIC

The AV9110 requires a stable reference clock (5 to 32 MHz) to
generate a stable, low jitter output clock. The AV9 11 0 -01 is
optimized to use an external quartz crystal as a frequency
reference, without the need of additional external components.
The AV9110-02 is optimized to accept an TTL clock
reference. Either device can be used with an external crystal
or accept a TTL clock reference, although extra components
may be required. The various combinations implied are
summarized in Figure 2 (see page 7).
