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 4321 XS includes an identification circuitry with analog output.
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
≥
80dB). An STS output with adjustable
threshold and stop window is available.
