Closed-Loop Voltage Gain vs Frequency

Double Terminated Cable Driver

When driving a cable it is important to terminate the cable

to avoid unwanted reflections. This can be done in one of

two ways: single termination or double termination. With

single termination, the cable must be terminated at the

receiving end (75

Ω to ground) to absorb unwanted en-

ergy. The best performance can be obtained by double

termination (75

Ω in series with the output of the amplifier,

and 75

Ω to ground at the other end of the cable). This
