Single wanted channel, 60 dBµV, at tuner input.
If this residual step is considered as limitating for the IC performances, refer to the Application Note AN1002 for compromise to
circumvent it.
Single wanted channel, 100 dBµV level, at tuner input.
Wanted channel being N, rejection of the N + n channel sound carrier for analog reception.
Adjacent channel power rejection.
