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.
