13 TRANSMITTER PINS TX1 AND TX2
The signal delivered on TX1 and TX2 is the 13.56 MHz carrier frequency modulated by an envelope signal. It
can be used to drive an antenna directly, using a few passive components for matching and filtering (see
chapter 17). For that, the output circuitry is designed with an very low impedance source resistance. The
signal of TX1 and TX2 can be controlled via the TxControl Register.
13.1 Configuration of TX1 and TX2
The configuration possibilities of TX1 are described in the table below:
The configuration possibilities of TX2 are described in the table below:
13.2 Operating Distance versus Power Consumption
The user has the possibility to find a trade-off between maximum achievable operating distance and power
consumption by using different antenna matching circuits as described in Error! Reference source not
found. and/or by varying the supply voltage at the antenna driver supply pin TVDD.
