High-performance multi-protocol full NFC Forum-compliant frontend
With the options “RF high side push” and “RF low side push”, potentially faster fall times
can be achieved for the antenna voltage amplitude at the beginning of a modulation. This
basic behavior during modulation cannot be configured independently for TX1 and TX2.
Only the clock polarity can be configured separately with TX1_INV_RM and
TX2_INV_RM.
11.8.3.2
10 % Amplitude Modulation
For a targeted ASK 10 % amplitude modulation, the bits RF_CONTROL_TX_CLK in
register TX_CLK_MODE_RM need to be set to value 0b111. Then the signal envelope
does not influence the clock behavior thus resulting in an ASK modulation to a modulation
index as defined by RF_CONTROL_TX in the bits TX_RESIDUAL_CARRIER. The
residual carrier setting is used to adjust the modulation degree at the TX output. A control
loop is implemented to keep the modulation degree as constant as possible.
The settings and resulting typical residual carrier and modulation degree is given in table
below:
110
RF high side push
Open-drain, only high side (push) MOS
supplied with clock, clock polarity defined by
TX2_INV_RM; low side MOS is off
101
RF low side pull
Open-drain, only low side (pull) MOS
supplied with clock, clock polarity defined by
TX1_INV_RM; high side MOS is off
111
13.56 MHz clock derived
from 27.12 MHz quartz
divided by 2
push/pull Operation, clock polarity defined
by invtx; setting for 10 % modulation
