ISO/IEC 14443 A Reader IC
If an external clock source is used, the clock signal must be applied to pin OSCIN. In this
case, be very careful in optimizing clock duty cycle and clock jitter. Ensure the clock
quality has been verified. It must meet the specifications described in
Section 13.4.5 on
page 95
.
Remark:
We do not recommend using an external clock source.
9.9 Transmitter pins TX1 and TX2
The signal on pins TX1 and TX2 is the 13.56 MHz energy carrier modulated by an
envelope signal. It can be used to drive an antenna directly, using minimal passive
components for matching and filtering (see
Section 15.1 on page 96
). To enable this, the
output circuitry is designed with a very low-impedance source resistance. The TxControl
register is used to control the TX1 and TX2 signals.

9.9.2
Antenna operating distance versus power consumption
Using different antenna matching circuits (by varying the supply voltage on the antenna
driver supply pin TVDD), it is possible to find the trade-off between maximum effective
operating distance and power consumption. Different antenna matching circuits are
described in the Application note
“MIFARE Design Matching Circuit and Antennas”
