8.3 Receiver
8.3.1 Interfacing to the Line
The receiver can be transformer-coupled or capacitor-coupled to the line. Typically, the receiver interfaces to the
incoming coaxial cable (75
Ω) through a 1:1 isolation transformer. The receive line termination can be internal to the
device, external to the device, or a combination of both. Figure 4-1 shows the arrangement of the transformer when
the internal termination is enabled (LIU.CR2:RTRE = 1) and no external termination resistors are used. Figure 4-2
shows the arrangement of the transformer and external termination resistors when the internal termination is
disabled (LIU.CR2:RTRE = 0). The internal termination resistor value is specified in LIU.CR2:RRESADJ[3:0]. Table
8-7 and Table 8-8 specify the required characteristics of the transformer and provide a list of recommended
transformers. The receiver expects the incoming signal to be in B3ZS- or HDB3-coded AMI format.

8.3.2 Optional Preamp
The receiver can be used in monitoring applications that typically have series resistors with a resistive loss of
approximately 20dB. When the RMON pin is high or the LIU.CR2:RMON configuration bit is set, the receiver can
compensate for this resistive loss by applying 14dB of additional flat gain to the incoming signal before sending the
signal to the AGC/equalizer block (an additional 6dB of flat gain is applied in the AGC circuitry for a total gain of
20dB). When the preamp is enabled the receiver automatically determines whether or not to make use of the
preamp’s additional gain. Status bit LIU.SR:RPAS indicates whether or not the preamp is in use. A change of state
8.3.3 Automatic Gain Control (AGC) and Adaptive Equalizer
The AGC circuitry applies flat (frequency independent) gain to the incoming signal to compensate for flat losses in
the transmission channel and variations in transmission power. Since the incoming signal also experiences
frequency-dependent losses as it passes through the coaxial cable, the adaptive equalizer circuitry applies
frequency-dependent gain to offset line losses and restore the signal. The AGC/equalizer circuitry automatically
adapts to coaxial cable losses from 0 to 22dB, which translates into 0 to 457 meters (1500 feet) of coaxial cable
