Application Scenarios & Design Considerations

Digital TV sound demodulator/decoder

Alternative Part Number

  • MSP3410G --: Multistandard sound IF processor with similar audio demodulation and processing functions, commonly used as a drop-in alternative in TV chassis designs.
  • TDA9808T --: Single standard sound IF demodulator from the same vendor family lineage, suitable for audio IF processing where the full multistandard feature set of the TDA9874H is not required.
  • LA75503V --: TV sound IF and audio processing IC covering similar demodulation tasks, usable as a functional substitute in analog TV audio stages.
  • TDA9875AH --: Same TDA987x audio/video processor family from the original Philips/NXP line, offering comparable multi-standard sound IF and audio processing functions with a similar pinout, making it the closest functional drop-in candidate.
  • TDA9873H --: Earlier member of the same Philips TDA987x sound processor series with closely related demodulation and audio switching features; suitable when the extra functions of the TDA9874H are not required.
