Overview

The ADV3221-EVALZ/ADV3222-EVALZ User Guide (UG-844) provides documentation for evaluating the ADV3221 and ADV3222 high-speed, buffered 4:1 analog multiplexers. The evaluation board supports both 50 Ω and 75 Ω signal paths on a single PCB, facilitating performance testing for various signal environments. These devices feature a -3 dB bandwidth exceeding 800 MHz, channel switching times under 20 ns, and low crosstalk (-58 dB at 100 MHz). The ADV3221 offers a gain of +1, while the ADV3222 offers a gain of +2. The document includes detailed hardware descriptions, ±5 V power supply requirements, digital logic truth tables for channel selection, full circuit schematics, PCB artwork, and a complete bill of materials.

Use Cases

  • High-speed signal switching
  • Video routing and distribution
  • Signal multiplexing in communication equipment
  • RF and video test systems
  • Evaluating buffered analog multiplexers
