Explanation
Equivalent Circuit
11
OUT2
2.5
(4.7)
Output pin of video amplifier.
In case of RL = 1 k
, differential output
voltage equal 3 VP-P.
OUT1 and INA are same phase.
OUT2 and INB are same phase.
11
OUT1
2.5
(4.7)
13
Vcc2
5 to 9
Power supply pin of video amplifier.
Must be connected bypass capacitor to
minimize ground impedance.
14
INB
2.5
(4.1)
Signal input pin of video amplifier.
This pin is high impedance.
15
INA
2.5
(4.1)
16
G1B
1.7
(3.3)
Gain control pin of video amplifier.
Maximum gain at G1A-GIB = short.
Minimum gain at G1A-G1B = open.
Gain is able to adjust by inserting arbitrary
resistor between 16pin and 17pin.
17
G1A
1.7
(3.3)
18
MIX
OUT1
3.7
Output pin of mixer.
This output pin features low-impedance
because of its emitter-follower output port.
19
MIX
OUT2
3.7
20
GND
0.0
Ground pin.
Must be connected to the system ground
with minimum inductance.
Ground pattern on the board should be
formed as wide as possible.
