Operation notes
(1) Simultaneous audio and video output muting function
It is possible to simultaneously mute the audio and video output by pulling the AFC filter terminal down.
(2) AFT defeat function
AFT defeat can be applied by pulling the AFT coil terminal down via a 1k
resistor.
(3) Recommended SIF input range for intercarrier mode
P / S = 20 TO 30dB (including SAWFILTER).
(4) IF input range for RFAGC switching
60 TO 95dB
μ
.
(5) Intercarrier mode switching
Intercarrier mode can be set by pulling the SIF terminal down via a 2k
resistor.
(6) IR terminal external resistor
This resistor sets the filter system reference current, so use an accurate component that has good temperature char-
acteristics.
