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 VINPUT=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 VINPUT ≤ 1mV.

3. Check the BPF checkpoint signal level when

VINPUT=3 to 6mV or greater RDS signal.

No.3988–4/6
