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:
One possible Solution:
t
This gives 15ms ON time of a total period of 150ms which results in max. 0.9mA mean current
consumption in Self Polling Mode. The resulting worst case timing is shown in the following figure:
