21.5 Examples of ISO14443A Analog- and Digital Test Signals

Fig. 22 shows a MIFARE Classic Card’s answer to a request command using the Qclock receiving path.

RX –Reference is given to show the Manchester modulated signal at the RX pin. This signal is demodulated

and amplified in the receiver circuitry VRXAmpQ shows the amplified side band signal having used the Q-

Clock for demodulation. The signals VCorrDQ and VCorrNQ generated in the correlation circuitry are

evaluated and digitised in the evaluation and digitizer circuitry. VEvalR and VEvalL show the evaluation

signal of the right and left half bit. Finally, the digital test-signal S_data shows the received data which is

send to the internal digital circuit and S_valid indicates that the received data stream is valid.
