TDA4480-D processor equivalent, multi standard quasi parallel-sound processor.
D High signal sensitivity D Simple filter configuration and few external
components
D VCO controlled mixer stage converts intercarrier frequencies of different standards.
Audio carrier signal (simple or double carrier, FM and AM) is applied via three stage AGC controlled broad band amplifi.
