Note: All absolute times assume TC = 1 / fC = 8 μs (fC = 125 kHz)
Note: All absolute times assume TC = 1 / fC = 8 µs (fC = 125 kHz)
Note: These timings are from the datasheet and doesn't map the best to the features of the RVD4 LF antenna.
RDV4 LF antenna has high voltage and the drop of power when turning off the rf field takes about 1-2 TC longer.
