Figure 13: Average Slice Mode Waveform
The peak mode also generates a threshold value automatically. This generated threshold is used to compare to the output of the slice
circuit to re-create the digital data. The slice circuit uses an external capacitor with an internal peak detector to form the peak value of
the data waveform. A 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. Refer to AMIS application note “Setting Up the Data Slicing Modes” for more information. Figure 14 shows a typical
waveform for the Peak mode.
Table 26 shows the control registers for the auto slice modes.
