ADV3203ASWZ

Overview

The ADV3203ASWZ is a 300 MHz, 32 × 16 buffered analog crosspoint switch manufactured by Analog Devices Inc. It features a selectable gain of +2 and supports single +5 V or dual ±2.5 V/±3.3 V supplies. The device includes a 2:1 on-screen display (OSD) insertion mux per output and an input sync-tip clamp for AC-coupled applications. It 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.
• Includes a 2:1 OSD insertion multiplexer at each output for video overlay applications.
• Supports serial programming via a double-buffered shift register for daisy-chaining multiple devices.
• Integrates an input sync-tip clamp to facilitate AC-coupled signal processing.

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 suffix ASWZ against official documentation to confirm it denotes the standard commercial/industrial grade variant without unique functional deviations. Ensure the ordering part number matches the exact package type and temperature rating required for the target application environment.

Selection Notes

Select the ADV3203ASWZ when a fixed voltage gain of +2 is required for back-terminated load applications. Verify that the system power architecture supports dual ±2.5 V or ±3.3 V supplies, as this configuration is necessary for the specified gain operation compared to the single-supply ADV3202.

Part Context

This component belongs to the ADV3202/ADV3203 family of analog crosspoint switches. While the ADV3202 provides unity gain (+1), the ADV3203 variant specifically offers a gain of +2. Both share identical pinouts and control logic, allowing for flexible design choices based on signal termination requirements.

Replacement Considerations

The ADV3202ASWZ serves as a direct pin-compatible alternative if a gain of +1 is preferred over +2. For expanded matrix capacity, the 32 × 32 ADV3200/ADV3201 series offers a compatible footprint with increased I/O counts.
