TYPICAL APPLICATIONS
The ADM2490E transceiver is designed for point-to-point transmission lines. Figure 26 shows a full-duplex point-to-point application.
To minimize reflections, terminate the line at the receiver end with a termination resistor. The value of the termination resistor should be
equal to the characteristic impedance of the cable.
