Notes to the AC characteristics
1.
Intermodulation suppression (BFC: Beat Frequency Components).
a)
α
2 = V
o(signal)
(at 1 kHz)/V
o(spurious)
(at 1 kHz); f
s
= (2
×
10 kHz)
19 kHz.
b)
α
3 = V
o(signal)
(at 1 kHz)/V
o(spurious)
(at 1 kHz); f
s
= (3
×
13 kHz)
38 kHz.
c) Measured with 91% mono signal; f
mod
= 10 or 13 kHz; 9% pilot signal.
2.
Traffic radio (VF) suppression.
a)
α
57(VF) = V
o(signal)
(at 1 kHz)/V
o(spurious)
(at 1 kHz
±
23 Hz).
b) Measured with 91% stereo signal; f
mod
= 1 kHz; 9% pilot signal.
c) 5% traffic subcarrier (f = 57 kHz; f
mod
= 23 Hz AM, m = 0.6).
3.
SCA (Subsidiary Communication Authorization).
a)
α
67 = V
o(signal)
(at 1 kHz)/V
o(spurious)
(at 9 kHz); f
s
= (2
×
38 kHz)
67 kHz.
b) Measured with 81% mono signal; f
mod
= 1 kHz; 9% pilot signal.
c) 10% SCA subcarrier (f
s
= 67 kHz, unmodulated).
4.
ACI (Adjacent Channel Interference).
a)
α
114 = V
o(signal)
(at 1 kHz)/V
o(spurious)
(at 4 kHz); f
s
= 110 kHz
(3
×
38 kHz).
b)
α
190 = V
o(signal)
(at 1 kHz)/V
o(spurious)
(at 4 kHz); f
s
= 186 kHz
(5
×
38 kHz).
c) Measured with 90% mono signal; f
mod
= 1 kHz; 9% pilot signal; 1% spurious signal (f
s
= 110 kHz or 186 kHz,
unmodulated).
5.
R
L
is the AC impedance of the external circuitry at 1 kHz connected to the audio outputs in the application. There is
also no DC current flowing through R
L
.
6.
The load capacitance is the sum of the series connection of C
×
1 and C
×
2 (see Fig.11) and the parasitic parallel
capacitor of the crystal C
p
.
