4.5 Data Slicer Threshold Generation
The threshold of the data slicer especially for a coding scheme without DC-con-
tent, 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 Manches-
ter coding the threshold can be generated using an external R-C integrator as
shown in Figure 4-5. The time constant T
A
of the R-C integrator has to be sig-
nificantly larger than the longest period of no signal change T
L
within the data
sequence. In order to keep distortion low, the minimum value for R is 20k
.

Data Slicer Threshold Generation with External R-C Integrator
Another possibility for threshold generation is to use the peak detector in con-
nection 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.
