Output pins for the video amplifier. With R
the differential output voltage is 3 Vp-p. OUT1 and
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.
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.
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.
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.
Output pins for the downconverter. These are emitter
follower outputs which feature low impedance. In the
case of a single-ended output, bypass the unused
pin to ground through a capacitor.
Ground pin. This pin must be connected to system
ground. Form ground pattern as wide as possible
to minimize ground impedance.
