The threshold of the data slicer especially for a coding scheme without DC-content, can be generated in two ways,
depending on the signal coding scheme used. In case of a signal coding scheme without DC content such as
Manchester coding the threshold can be generated using an external RC-Integrator as shown in
time constant
within the data sequence. In order to keep distortion low, the minimum value for
Figure 9
Another possibility for threshold generation is to use the peak detector in connection with two resistors and one
capacitor as shown in the following figure. The component values are depending on the coding scheme and the
protocol used.
