DET circuit
This circuit carries out phase detection on the signal se-
lected and amplified by the BPF, and holds it at the peak
level. It is configured so that all of the capacitors are inter-
nal.
The charge that was charged by the internal capacitors
in the DET circuit is set to be discharged at 75ms / V
(Typ.), but in order to eliminate any effects of disparity, a
reset circuit is also included.

Output section circuit
The signal level held at peak level by the DET undergoes
V / I conversion and is output. Since the next stage sup-
ports MOS (high-input impedance), there is a resistance
of 33.9k (44.3k for REC output only) between the out-
put pin and the GND in the IC, so the output value
changes based on the input impedance.
