MAX7463USA+T

Video Processing Overview

The MAX7463USA+T is a single-channel, standard-definition video reconstruction filter and buffer manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and features a fixed output buffer gain of +6dB. The device provides a flat passband response out to 5MHz with a stopband attenuation of -43dB at 27MHz. It is capable of driving two standard 150Ω AC-coupled or DC-coupled video loads, maintaining an output black level of less than 1V for DC-coupled applications.

Video Processing Feature Summary

• Integrates a fourth-order Butterworth-type lowpass filter optimized for NTSC, PAL, and SDTV bandwidths.
• Provides a fixed +6dB output buffer gain suitable for standard definition video signal processing.
• Capable of driving dual 150Ω video loads while maintaining a low output blanking level below 1V.

Video Processing Applications

• Cable, satellite, and terrestrial set-top boxes
• Digital video recorders (DVRs)
• Hard-disk recorders

Video Processing Procurement Notes

Verify the specific ordering suffix '+T' against the manufacturer's current documentation to confirm tape-and-reel packaging status. Confirm that the 'USA' package designation corresponds to the 8-pin SO format as detailed in the official datasheet tables. Ensure compatibility with the required +5V operating voltage and temperature range specifications before finalizing procurement.

Video Processing Selection Notes

Select the MAX7463USA+T when a fixed +6dB gain is required for standard-definition video reconstruction. This component is appropriate for applications needing anti-aliasing and digital-to-analog smoothing without the need for selectable gain settings or output disable functions found in the MAX7462 variant. It fits designs requiring a compact 8-pin SO package.

Video Processing Part Context

This component belongs to the MAX7462/MAX7463 family of single-channel video reconstruction filters and buffers. While the MAX7462 offers selectable gain and an output disable feature, the MAX7463 simplifies the design by providing a fixed +6dB gain configuration. Both devices share identical filter characteristics and are designed for reconstructing analog video from digital data sources.

Video Processing Replacement Considerations

The MAX7462UUA and MAX7462USA serve as functional alternatives within the same family, offering selectable gain (+6dB/+9.5dB) and an output disable pin. These parts require additional external control logic for gain selection but provide flexibility not available in the fixed-gain MAX7463.

Video Processing FAQ

What is the maximum frequency response of the MAX7463?

The device features a flat passband response out to 5MHz and provides a stopband attenuation of -43dB at 27MHz.

Can the MAX7463 drive DC-coupled video loads?

Yes, the output buffer can drive DC-coupled loads while maintaining an output blanking level of less than 1V, complying with digital TV interface specifications.
