Figure 13: Average Slice Mode Waveform
In the Peak mode, a threshold value is generated automatically as well. This threshold value is then compared to the output of the slice
circuit to re-create the digital data. The operation of the slice circuit is based on an external capacitor with an internal peak detector, in
order to arrive at the peak value of the data waveform. The threshold value is set 6dB below this peak value. The capacitor value
should be selected so that the peak detector does not discharge during periods of continuous zeros, while being small enough to allow
the peak detector to reach the peak value quickly. For further details, refer to the application note titled “Setting Up the AMIS-52150
Data Slicing Modes”. Figure 14 shows a typical waveform for the Peak mode.
