( ) is value
at V CC = 9V
11
OUT2
2.5
(4.7)
Output pins for the video amplifier. With R L = 1k ? ,
the differential output voltage is 3 Vp-p. OUT1 and
13
INA are in phase. OUT2 and INB are in phase. In
the case of a single-ended output, bypass the unused
pin to ground through a capacitor.

OUT1
2.5

(4.7)
13
V CC 2
5~9
Supply voltage pin for the video amplifier block. This
pin should be connected with a bypass capacitor
(e.g., 1000 pF) to minimize ground impedance.
14
INB
2.5
(4.1)
Input pins for the video amplifier. These pins have
high impedance. In the case of a single-ended input,
bypass the unused pin to ground through a capacitor.

2.5
(4.1)
16
G1B
1.7
(3.3)
Gain control pins for the video amplifier. The gain
may be adjusted by varying the value of the resistor
between pins 16 and 17. Maximum gain = short;
Minimum gain = open.
REG
17
G1A
1.7
(3.3)
18
MIX OUT1
3.7
Output pins for the downconverter. These are emitter
follower outputs which feature low impedance. In the
4
case of a single-ended output, bypass the unused
pin to ground through a capacitor.
18
19
MIX OUT2
3.7
19
REG
20
GND
0.0
Ground pin. This pin must be connected to system
ground. Form ground pattern as wide as possible
to minimize ground impedance.
