Active antenna concept

[Prabin]

Hi ,

we are working on NFCB tag and want to use “Active antene concept” of CLRC663 to validate our digital without  RF. However we have following doubts while using this mode .

1) Is there any documentation on this topic?

2) when SIGIN pin is configured to receive generic (i.e. Rcv.SigInSel = 11) , should we send digital subcarrier waveform (847khz) or baseband (106khz) signal ?

3) Should signal on SIGIN include SOF, EOF?

4) Do we need to synchronise the signal on SIGIN with readers’s fC?

 Thanks,

Prabin

Hello,

Unfortunately, there is only the datasheet mentioned about the Active Antenna concept. There is no example and more document for your reference.
