THE RECEIVE SECTION
Figure 6 indicates that the Receive Section in the
XRT73L02 consists of the following blocks:
AGC/Equalizer
Peak Detector
Slicer
Clock Recovery PLL
Data Recovery
HDB3/B3ZS Decoder
The purpose of each Receive Section of the
XRT73L02 is to take an incoming attenuated/distort-
ed bipolar signal from the line and encode it back into
the TTL/CMOS format where it can be received and
processed by the Terminal Equipment.

INE
The design of the Receive Circuitry in the XRT73L02
allows for transformer-coupling or capacitive-coupling
of the Receive Section to the line. As mentioned ear-
lier, the specification documents for E3, DS3 and
STS-1 all specify 75 Ohm termination loads when
transmitting over coaxial cable. The recommended
method of Transformer-Coupling the Receive Section
of the XRT73L02 to the line is shown in Figure 15 and
the Capacitive-Coupling method is shown in Figure
16.
