LA7567BVA
First SIF AGC filter connection
This IC adopts an average value AGC system. The
first SIF conversion gain is about 30dB and the
AGC range is over 50 dB. Normally, a 0.01F
capacitor should be used for the filter at this pin.
If an intercarrier is used, connect this pin to
ground. An IC internal switch will be set so that
the intercarrier output becomes the SIF converter
input.

IF AGC filter connection
The signal which is peak detected by the internal
AGC detector is converted to the AGC voltage at
pin 17. Furthermore, this IC includes a second
AGC filter (lag-lead filter) used to create the dual
time constants internally in the IC.
Use a 0.022F capacitor as this external capacitor.
However, this capacitor value must be adjusted
according to the sag, AGC peak, and other
characteristics.
