milliseconds, and repeated every 1 second, is applied to
MCI (Trace #I). Trace #2 is the output at TXO, and is
approximately 650 mVp-p at its maximum. Trace #4 is
the output at RXO, and is approximately 2.2 mVp-p at
its maximum. The time to switch from the receive mode
to the transmit mode is approximately 40 ms, as
indicated by the time required for TXO to turn on, and
for RXO to turn off. After the signal at MCI is shut off,
the switching time back to the receive mode is
approximately 210 ms.
applied to MCI (Trace #I), and a repetitive burst signal
of 100 mVp-p is applied to RXI (Trace #3), lasting
approximately 120 ms, and repeated every 1 second.
In Figure 17, a continuous signal of 7.6 mVp-p is

mVp-p at its maximum, and Trace #4 indicates the
output at RXO, and is approximately 150 mVp-p at its
maximum. In this sequence, the circuit switches between
the idle and receive modes. The time required to switch
from idle to receive is approximately 70 ms, as indicated
by the first part of Traces 2 and 4. After the receive
signal is shut off, the time to switch back to the idle
mode is approximately 100 ms.
