PREFACE
The video twisted-pair transmitter TTM 101C is a
correction amplifier with the standard
asymmetrical video input and symmetrical output
which is adjusted to connect the twisted-pair
cable. It has very small dimensions and very low
power consumption. The choice of output
impedance allows the use of different kinds of
cables.
FEATURES
very small dimensions
simple
installation
AC/DC power supply
very low power consumption
over-voltage
protection
dual output impedance
pre-em10 dB / 5 MHz
BLOCK DIAGRAM
PRINCIPLE OF OPERATION
The input is closed with the impedance of 75
.
Then follows the stage which defines the pre-
emphasis. By means of the amplifier stage two
signals separated by 180
appear on the output A
and B.
The output impedance jumper enables a choice of
output impedance - 125
or 90
.
The power is supplied by connecting to the AC or
DC power supply unit.
