In the Application Information Section of the datasheet for the OPA356 it states :
"The OPAx356 output stage is capable of driving a standard back-terminated 75Ω video cable. By back-terminating a transmission line, it does not exhibit a capacitive load to its driver. A properly back-terminated 75Ω cable does not appear as capacitance; it presents only a 150Ω resistive load to the OPAx356 output."
What does the term "back termination" mean?
