Figure 1 indicates that the XRT7300 Receive Section
consists of the following blocks:
AGC/Equalizer
Peak Detector
Slicer
Clock Recovery PLL
Data Recovery
HDB3/B3ZS Decoder
The purpose of the XRT7300 Receive Section is to
take an incoming attenuated/distorted bipolar signal
from the line and encode it back into the TTL/CMOS
format where it can be received and processed by
digital circuitry in the Terminal Equipment.

By design, the Receive Section of the XRT7300 can
be transformer-coupled or capacitive-coupled to the
line. The specification documents for E3, DS3 and
STS-1 all specify 75Ohm termination loads when
transmitting over coaxial cable. It is recommended to
