20.4 PRBS
Note: The DAC has a current output, it is recommended to use a 1 kΩ pull-down
resistance at pins AUX1/AUX2.
Enables the PRBS9 or PRBS15 sequence according to ITU-TO150. To start the
transmission of the defined datastream the command send has to be activated. The
preamble/Sync byte/start bit/parity bit are generated automatically depending on the
selected mode.
Note: All relevant register to transmit data have to be configured before entering PRBS
mode according ITU-TO150.
The figure below shows a typical circuit diagram, using a complementary antenna
connection to the PN512.
The antenna tuning and RF part matching is described in the application note “NFC
Transmission Module Antenna and RF Design Guide”.
