ADV3201ASWZ

Overview

The ADV3201ASWZ is a 32 × 32 buffered analog crosspoint switch manufactured by Analog Devices Inc. It features a selectable gain of +2, making it suitable for back-terminated load applications. The device operates on a single 5 V supply or dual ±2.5 V / ±3.3 V supplies, consuming approximately 260 mA with all outputs enabled. Key electrical parameters include a −3 dB bandwidth exceeding 300 MHz at small signal levels and a slew rate greater than 400 V/μs. It incorporates a serial programming interface, input sync-tip clamps, and per-output 2:1 OSD insertion multiplexers. The component is housed in a 176-lead exposed pad LQFP package.

Feature Summary

• Nonblocking 32 × 32 switch array with integrated input buffers and output amplifiers
• Serial digital control interface supporting daisy-chaining of multiple devices
• Per-output 2:1 multiplexer for on-screen display (OSD) graphic insertion
• High impedance output disable capability to minimize bus loading in parallel configurations

Applications

• CCTV surveillance systems
• Composite video routing including NTSC, PAL, S, and SECAM standards
• RGB and component video routing for high-definition applications
• Video conferencing equipment

Procurement Notes

Verify the specific suffix ASWZ against the manufacturer's current ordering guide to confirm package type and temperature range. Ensure compatibility with the required power supply configuration, as the ADV3201 requires dual supplies for G = +2 operation. Confirm that the design supports the 176-lead LQFP footprint and thermal management requirements specified in the datasheet.

Selection Notes

Select the ADV3201ASWZ when a voltage gain of +2 is required for driving back-terminated loads. Compare against the ADV3200 if a gain of +1 is sufficient. Consider the pin-compatible ADV3202 and ADV3203 if a smaller 32 × 16 matrix is needed. Verify that the system can accommodate the serial control logic and the specific power supply rails necessary for the selected gain setting.

Part Context

The ADV3201ASWZ belongs to the ADV320x family of analog crosspoint switches from Analog Devices. This series includes the ADV3200 (G = +1), ADV3201 (G = +2), and the 32 × 16 variants ADV3202 and ADV3203. All members share a similar architecture but differ in gain and matrix size, allowing for flexible system scaling while maintaining pin compatibility within their respective groups.

Replacement Considerations

The ADV3200ASWZ is a direct pin-compatible alternative offering a gain of +1 instead of +2. For reduced channel counts, the ADV3202ASWZ and ADV3203ASWZ provide 32 × 16 configurations with gains of +1 and +2 respectively. These parts maintain the same package and control interface.
