Target Applications

  • The TEF665X is a single tuner AM/FM receiver for automotive applications and supports analog AM/FM and HD/DRM reception (HD/DRM is supported in TEF6659 only).
  • Additionally, due to a common technology platform, the TEF665X can be combined with TEF701X, SAF775X and SAF360X for optimal system application through common crystal oscillator sharing.
