The IC TEA 6840 and its derivative versions TEA 6845 / 6846 are for small
dimensioned Electronic Tuned AM/FM Car Radio receiver in global applications.
They carry the following functions:
* AM receiver for long-, medium- and short- wave (up to 49 m) with
. noise-blanking and weak signal control.
* FM receiver with
. image cancelling on chip;
. world-wide FM- application flexibility;
. keyed AGC;
. weather band included.
* A fast tuning Synthesizer with on chip control for inaudible RDS-AF updating.
* Digital Automatic Alignment for FM- RF circuit and for RF-fieldstrength indication.
AM and FM operate with high application flexibility, given by peripheral components
and by software control via I2C-bus.
