General Description

The AV9108 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.

Features

• Runs up to 80 MHz at 3.3V

• 50/50 typical duty cycle at 5V

• ±250ps absolute jitter

• Generates frequencies from 2 to 140 MHz

• 2 to 32 MHz input reference frequency

• Up to 16 frequencies stored internally

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

• Provides reference clock and synthesized clock

• On-chip loop filter

• Low power 0.8µ CMOS technology

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