ADV3200ASWZ

Overview

The ADV3200ASWZ is a 32 × 32 buffered analog crosspoint switch matrix in a 176-lead LQFP package. It provides nonblocking switching with selectable gain of +1 (ADV3200) or +2 (ADV3201). The device features a serial control interface, an on-screen display insertion mux, and input sync-tip clamp for AC-coupled applications. High impedance output disable allows paralleling outputs with minimal loading. It operates from single 5 V, dual ±2.5 V, or dual ±3.3 V supplies, consuming 1.25 W. Key performance metrics include >300 MHz bandwidth, 60 MHz 0.1 dB gain flatness, and -48 dB crosstalk at 5 MHz.

Feature Summary

• Large 32 × 32 nonblocking switch array with high impedance output disable capability
• Serial programming interface supporting daisy-chaining of multiple devices
• Integrated 2:1 OSD insertion mux per output channel
• Selectable sync-tip clamp input for AC-coupled signal processing

Applications

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

Procurement Notes

Verify the specific ordering suffix ASWZ against the manufacturer's current datasheet to confirm pinout and package dimensions match your design requirements. Ensure supply voltage configurations align with the selected gain setting before procurement.

Selection Notes

Select the ADV3200 variant for unity gain (+1) applications or the ADV3201 variant for gain of +2. Confirm that the required power supply configuration (single 5 V or dual ±2.5 V/±3.3 V) matches the system architecture. Verify thermal management capabilities given the 16°C/W junction-to-ambient resistance.

Part Context

This component belongs to the ADV3200/ADV3201 family of buffered analog crosspoint switches. It shares functional similarities with the ADV3202 and ADV3203, which are pin-compatible 32 × 16 versions. The series is designed for high-density video routing applications requiring low distortion and high isolation.

Replacement Considerations

The ADV3202 and ADV3203 are pin-compatible alternatives offering a 32 × 16 configuration. Direct substitution requires verifying if the reduced channel count meets system requirements and confirming gain settings match the application needs.
