Sample Application Circuit Using the LA2232/M and the LC7073/M
Adjusting the 57 kHz BPF
(A) Check the output level of the bi-phase signal from pin 4 or pin 22 (with the pin 6 RDS input at about 1 mVrms and the ALC circuit not operating).
(B) Check the signal level of the BPF checkpoint (with the pin 6 RDS input in the range 3 to 6 mVrms or higher).
