ADV3202ASWZ

Overview

The ADV3202ASWZ is a 32 × 16 buffered analog crosspoint switch matrix manufactured by Analog Devices Inc. It features a selectable gain of +1 and supports single +5 V, dual ±2.5 V, or dual ±3.3 V power supplies. The device provides a bandwidth exceeding 300 MHz with a slew rate greater than 400 V/μs. It includes a 2:1 on-screen display insertion mux per output and an input sync-tip clamp for ac-coupled applications. The unit operates within an extended industrial temperature range of −40°C to +85°C and is housed in a 176-lead exposed pad LQFP package.

Feature Summary

• Features a large, nonblocking 32 × 16 switch array with high impedance output disable capability for minimal bus loading.
• Includes a 2:1 on-screen display insertion mux and an input sync-tip clamp for ac-coupled video applications.
• Supports serial programming via a double-buffered digital control interface allowing daisy-chaining of multiple devices.
• Provides excellent video performance with low differential gain error and low all-hostile crosstalk.

Applications

• CCTV surveillance systems
• Routing of composite video signals (NTSC, PAL, S, SECAM)
• RGB and component video routing
• Video conferencing equipment

Procurement Notes

Verify the specific ordering suffix ASWZ against official documentation to confirm package type and tape/reel specifications. Confirm supply voltage requirements match the application design, as the ADV3202 supports both single and split supply configurations. Ensure thermal management meets the junction temperature limits specified in the datasheet for the selected operating environment.

Selection Notes

Select the ADV3202 when a gain of +1 is required for back-terminated load applications. Compare against the ADV3203 if a gain of +2 is necessary. Consider the ADV3200 or ADV3201 if a 32 × 32 pin-compatible configuration is needed. Verify that the 176-lead LQFP package fits the PCB layout constraints and thermal dissipation requirements.

Part Context

The ADV3202 is part of the ADV320x series of analog crosspoint switches from Analog Devices. It shares architectural similarities with the ADV3203, differing primarily in output gain. The series is designed for high-density video routing applications requiring low distortion and high bandwidth. It serves as a core switching component in professional video distribution infrastructure.

Replacement Considerations

The ADV3203 is a pin-compatible alternative offering a gain of +2 instead of +1. For larger arrays, the ADV3200 and ADV3201 provide 32 × 32 configurations with identical pinouts. Verify electrical compatibility regarding gain and supply voltage before substitution.
