General Description

The AV9107C offers a tiny footprint solution for generating two simultaneous clocks. One clock, the REFCLK, is a fixed output frequency which is the same as the input reference crystal (or clock). The other clock, CLK1, can vary between 2 and 120 MHz, with up to 16 selectable preprogrammed frequencies stored in internal ROM (frequency range depends on design option).

Features

● Patented on-chip Phase-Locked Loop with VCO for clock generation

● Provides reference clock and synthesized clock

● Generates frequencies from 2 to 120 MHz (depending on option), operates to 80 MHz for VDD 3.3V±10

● 8-pin DIP or SOIC package or 14-pin DIP or SOIC package

● 2 to 32 MHz input reference frequency (depending on option)

● On-chip loop filter

● Up to 16 frequencies stored internally

● Low power CMOS technology

● Single ±3.3 or +5 volt power supply

Applications

Graphics: The AV9107C is the easiest to use, lowest cost, and smallest footprint frequency generator for graphics applications. It can generate up to 16 different frequencies, including all frequencies necessary for VGA standards. It should be used in place of the AV9105/6 when the reference clock is also needed.
