Description
Equivalent circuit
16
1st SIF AGC FILTER
First SIF AGC filter connection.
This IC adopts an average value AGC technique. The first
SIF conversion gain is about 30 dB, and the AGC range is
over 50 dB. A 0.01 F capacitor is normally used in filter
connected to this pin.
When used in an intercarrier system:
Connect this pin (pin 16) to ground. The IC internal switch
will operate to connect the intercarrier output to the SIF
converter input.
17
IF AGC FILTER
IF AGC filter connection
The signal peak-detected by the built-in AGC detector is
converted to the AGC voltage at pin 17. Additionally, a
second AGC filter (a lag-lead filter) used to create the dual
time constants is provided internally in the IC.
Use a 0.022-F capacitor as the external capacitor, and
adjust the value according to the sag, AGC speed, and
other characteristics.

VIF input
VIF amplifier input.
The input circuit is a balanced circuit, and the input circuit
constants are:
R
≈ 1.5 k
C
≈ 3 pF
