Overview
Integrated Circuit Systems, Inc.
AV9110 Serially Programmable Frequency Generator 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.
Block Diagram 9110 Rev F 5/30/00 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.
AV9110 Pin Configuration Clock Reference Implementations: AV9110-01 vs.
AV9110-02 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 TT...
