SoC for “CD-Less” Car Audio System Description0 The Fujitsu MB9G711 Series ASSP offers a low-cost System- on-a-Chip (SoC) solution for “CD-Less” car audio systems. The MB9G711 Series ASSP enables the decoding and playback of audio from portable MP3 players as well as from USB and SD interfaces. The chip supports the popular MP3, WMA, Ogg, and AAC audio formats. Applications0

  • Low-cost solution to add digital audio playback from a variety of devices to car audio systems.
  • Other applications include advanced car audio systems, data recording and industrial-control applications. Benefits0 The Fujitsu MB9G711 Series ASSP offers audio system designers the ability to create a “CD-Less” automotive audio entertainment system capable of pla ying the mos t popular digit al aud io files. By pr oviding the option to eliminate the CD player, the MB9G711 Series ASSP allows for low-cost designs that can be free from me- chanical f ailure, r equire less po wer, an d fit in a smaller f orm f actor. The gr eatest benefit of the MB9G711 Ser ies AS SP is in pr oviding plug-and-play suppor t f or digit al audio files. The c hip allo ws con sumers t o enjo y digit al audio files in their v ehicles dir ectly fr om their pref erred MP3 players without needing an FM transmitter or CD-R / CD-RW. Supported audio files can even be played back directl y from devices with a USB or SD interface, including USB thumb drives. Reference Design Features0 Fujitsu provides the LSI and a complete reference design pack- age, including source code for ready implementation. Available Now
