Differential Line Driver
Twisted pair transmission lines are more often being used for
high frequency analog and digital signals. Over long distances,
however, the attenuation characteristics of these lines can
degrade the performance of the transmission system. To com-
pensate for this, larger signals are transmitted, which after the
attenuation, will still have useful signal strength.
The high output current of two AD8010s can be used along
with a transformer to create a high power differential line driver.
The differential configuration effectively doubles the output
swing, while the step-up transformer further increases the out-
put voltage.
In the circuit in Figure 31 the A device is configured as a gain-
of-two follower, while the B device is a gain-of-two inverter.
These will produce a differential output signal whose maximum
value is twice the peak-to-peak value of the maximum output
of one device. For this circuit a 12 V peak-to-peak output can
be obtained.
The op amps drive a 1:2 step-up transformer that drives a
100
transmission line. Since the impedance reflected back to
the primary varies as the square of the turns ratio, it will appear
as 25
at the primary. This source terminating resistor is split
as a 12.4
resistor at the output of each device.
The circuit shown is capable of delivering 12 V p-p to the line
and operates with a –3 dB bandwidth of 40 MHz. The peak
current output of either op amp is 100 mA.
