Data Slicer Threshold Generation
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 Figure 9. The
time constant TA of the RC-Integrator has to be significantly larger than the longest period of no signal change TL
within the data sequence. In order to keep distortion low, the minimum value for R is 20 k.

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.
