APPLICATION INFORMATION
The MC1692 quad line receiver is used primarily to
receive data from balanced twisted pair lines, as indicated
in Figure 1. 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.
