Description
1st SIFOUT
Pin 21 is the 1st SIF output pin. The SIF
carrier output level is approximately
50 mVrms.
22
APC2 FILTER
Pin 22 is the APC2 filter pin. The filter
smoothes the output after comparing the
phase of VCO2 with that of VCO1 x 1/8 in
APC2.

23
RF AGC VR
Pin 23 is the RF AGC adjusting pin. The
adjustment point is where Rv approximates
15 k
. AV (audio/video) mute is effected by
dropping this pin to GND.
