Operating Information
57kHz Bandpass Filter Adjustment
1. Adjust the variable resistor connected to BPF-ADJ to
obtain the maximum signal level measured at I-DET
or BEF2.
2. When V
INPUT=1mV RDS signal, check I-DET or
BEF2 for a bi-phase output signal as shown in the
following figure. Note that the ALC circuit will not
operate when V
INPUT ≤ 1mV.
3. Check the BPF checkpoint signal level when
V
INPUT=3 to 6mV or greater RDS signal.
