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 of 400 megabits per second over an 18 foot twisted pair cable. The waveform picture of Figure 3 shows a 5.0 nanosecond pulse being propagated down the 18 foot line. The delay time for the line is 1.68 ns/foot. The MC1692 may also be applied as a high frequency schmitt trigger as illustrated in Figure 4. This circuit has been used in excess of 200 MHz. The MC1692 when loaded into 50 ohms will produce an output rising edge of about 1.5 nanoseconds.
