[1] The number column refers to the value in the number column of Table 30, Table 31 and Table 32.
Two CLRC632 devices configured as described in Table 33 can be connected to each
other using pins MFOUT and MFIN.
Remark: The active antenna concept can only be used at 106 kBd based on
ISO/IEC 14443 A.
9.11.2.2 Driving both RF parts
It is possible to connect both passive and active antennas to a single IC. The passive
antenna pins TX1, TX2 and RX are connected using the appropriate filter and matching
circuit. At the same time an active antenna is connected to pins MFOUT and MFIN. In this
configuration, two RF parts can be driven, one after another, by one microprocessor.
9.12 MIFARE higher baud rates
The MIFARE system is specified with a fixed baud rate of 106 kBd for communication on
the RF interface. The current version of ISO/IEC 14443 A also defines 106 kBd for the
initial phase of a communication between Proximity Integrated Circuit Cards (PICC) and
Proximity Coupling Devices (PCD).
To cover requirements of large data transmissions and to speed up terminal to card
communication, the CLRC632 supports communication at MIFARE higher baud rates in
combination with a microcontroller IC such as the MIFARE ProX.

The MIFARE higher baud rates concept is described in the application note: MIFARE
Implementation of Higher Baud rates Ref. 5. This application covers the integration of the
MIFARE higher baud rates communication concept in current applications.
