Application Scenarios & Design Considerations

3-channel 8-bit RGB D/A converter

Alternative Part Number

  • MB90092PF-G --: Fujitsu on-screen display controller in the same PFQ package family, commonly used as a functional substitute for Fuji OSD/character generator ICs.
  • MB88347PF --: Fujitsu video/OSD related IC in a similar QFP package, often cross-referenced for MB-series display controllers.
  • uPD6453CY --: NEC character generator/OSD controller with comparable function and package, a widely used alternative to Fuji MB-series OSD parts.
  • MB40978PF --: Same MB40978 series video DAC in the same QFP package but without the tape/reel suffix, so it is functionally identical and pin-compatible.
  • ADV7123KSTZ50 --: Triple 10-bit high-speed video DAC with similar resolution and speed, widely used as a drop-in replacement for Fujitsu video DACs in display applications.
  • THS8135PHP --: Triple 10-bit 240 MSPS video DAC offering comparable performance and interface, suitable as a cross-manufacturer alternative for the MB40978PFQ.
