Description
27
MRC control voltage time
constant
The MRC detector time constant
is determined by a 1-kresistor
and C2 when discharging and by
the 7-µA current and C2 when
charging.
Equivalent circuit
Pin 28
28
SNC control input
The sub-output is controlled by a
0 to 1-V input.
29
HCC control input
The high band frequency output is
controlled by a 0 to 1-V input.
It can also be controlled by the
MRC output.
Use a resistor of at least 100 k
when controlling with the pin 32
FM S-meter signal.
