TDA 4320X
2 Functional Description
The FM-IF demodulator TDA 4320X has been developed especially for car radio
applications. The on-chip multipath identification circuit activates an interference
suppression circuit in case of multipath interferences.
3 Circuit Description
The IC includes a 7-stage capacitive coupled limiter amplifier with coincidence
demodulator and AF output. The AF output signal can be continuously attenuated to
decrease the noise. In case of multipath interferences, the TDA 4320X includes an
identification circuitry. There is a field strength output (with min. 76 dB dynamic range,
typ. ± 1 dB nonlinearity and typ. ± 3 dB temperature drift), an IF counter output and an
adjustable muting (with full muting ≥ 80 dB).
