® : Usage of the MFIN and MFOUT
15.3.1 ACTIVE ANTENNA CONCEPT
The CL RC632 analog circuitry may be used via the pins MFIN and MFOUT. To do so, the following register
settings have to be made:

Table 15-5: Register setting to use the CL RC632 digital circuitry only
Two CL RC632 devices configured in the above described way may be connected to each other via the pins
MFOUT and MFIN.
Note: The usage of the active antenna concept is only possible with a baudrate of 106kbaud
according to ISO14443A.
15.3.2 DRIVING TWO RF-PARTS
It is possible, to connect a ‘passive antenna’ to pins TX1, TX2 and RX (via the appropriate filter and matching
circuit) and at the same time an Active Antenna to the pins MFOUT and MFIN.
In this configuration, two RF-parts may be driven (one after another) by one µ-Processor.
