Application Scenarios & Design Considerations

Digital TV Tuner IC 44-TSSOP -20 to 85

Alternative Part Number

  • LM1881MX/NOPB --: Video sync separator in a different TI series, functionally similar to the SN761640 video sync separator and widely available.
  • EL4583CSZ --: Sync separator IC from a different vendor and series, offering comparable sync separation functionality as a drop-in style alternative.
  • LMH1980MM/NOPB --: Auto-detecting video sync separator with similar function, different TI series naming, suitable when exact SN761640 matching is not required.
  • LMH1981MT --: Sync separator IC with similar video sync processing function, different series and package, suitable as a functional replacement in video timing applications.
  • EL4511CN --: Video sync separator and timing generator offering comparable sync extraction capability, different naming and vendor for easy distinction.
  • GS4981-CKA --: Sync separator IC used in video systems, provides similar sync separation function with a clearly different part series.
