Equalizer Control
The main objective of the equalizer is to amplify an input attenuated signal to a pre-determined amplitude that
is acceptable to the peak detector circuit. Using feedback from the peak detector, the equalizer will gain the
input up to the maximum value specified by the equalizer control bits, in the appropriate channel register,
normalizing the signal.
Once the signal has reached the pre-determined amplitude, the signal is then
processed within the peak detector and slicer circuit. A simplified block diagram of the equalizer and peak
detector is shown in Figure 6.

Cable Loss Indicator
The ability to monitor the cable loss attenuation of the receiver inputs is a valuable feature. The XRT83SL314
contains a per channel, read only register for cable loss indication. CLOS[5:0] is a 6-Bit binary word that
reports the value of cable loss in 1dB steps. An example of -15dB cable loss attenuation is shown in Figure 7.
