:
1. Figure 10 and Figure 11indicate that for 3.3 V oper-
ation, both 75
and 120
applications, the user
should connect a 9.1
resistor in series between
the TTIP/TRing outputs and the transformer.
2. Figure 10 and Figure 11indicate that the user
should use a 2 : 1 STEP-UP Transformer.
1.5
The design of the XRT82D20 permits the user to
transformer-couple the Receive Section to the line.
Additionally, as mentioned earlier, the specification
documents for E1 specify 75
termination loads,
when transmitting over coaxial cable, and 120
loads, when transmitting over twisted-pair. Figure 12
and Figure 13 present the various methods that the
user can employ to interface the Receiver of the
XRT82D20 to the line.
