APPLICATIONS INFORMATION

The ADM3061E/ADM3065E transceiver is designed for

bidirectional data communications on multipoint bus

transmission lines. Figure 47 shows a typical network

applications circuit.

To minimize reflections, terminate the line at both ends with a

termination resistor (the value of the termination resistor must

be equal to the characteristic impedance of the cable used) and

keep stub lengths off the main line as short as possible.
