The line is driven with a MC1660 OR/NOR gate. The MC1660 is terminated with 50 ohm resistors to –2.0 volts. At the end of the twisted pair a 100 ohm termination resistor is placed across the differential line receiver inputs of the MC1692. Illustrated in Figure 2 is the sending and receiving waveforms at a data rate o...
