Example for Self Polling Mode
The settings for Self Polling Mode depend very much on the timing of the transmitted Signal. To
create an example we consider following data structure transmitted in FSK.

Example for transmitted Data-structure
According to existing synchronization techniques there are some synchronization bursts in front of
the data added (code violation!). A minimum of 4 Frames is transmitted. Data are preferably
Manchester encoded to get fastest respond out of the Data Rate Detection.
Target Application:
- received Signal has code violation as described before
- total mean current consumption below 1mA
- data reception within max. 400ms after first transmitted frame
One possible Solution:
