Timing Characteristics
V
RF periods represent periods of the carrier frequency emitted by the transceiver unit.
See figure 12 for Synchronization pattern phases.
Due to amplitude modulation of the coil-signal, the clock-extractor may miss clocks or add spurious clocks
close to the edges of the RF-envelope. This desynchronization will not be larger than ± ± ± ± 3 clocks per bit and
must be taken into account when developing reader software.
