Downlink Operation The write sequence (downlink mode) of the TK5552 is shown in data into the transponder occurs by interrupting the RF field with short gaps. After the start gap the standard op code (11) is followed by the ...

Downlink Data Decoding The time between two detected gaps is used to encode the information. As soon as a gap is detected, a counter starts counting the number of field clock cycles until the next gap is detected. Depending ...

... The maximum distance between the base station and the TK5552 depends mainly on the base station, the coil geometries and the modulation options chosen (see “U2270B Antenna Design Hints” application note and the “U2270B” datasheet). When using Atmel’s U2270B demo board, typical distances in the range can be achieved. Maximum distance values which are generally valid can not be given in this datasheet ...
