For those interested, I've taken apart the case and did some
investigation how the FCDP hardware architecture looks like.

The results are available at

It seems the silicon tuner actually is intended for DVB-T, thus the
bandwidth it can down-convert is _much_ higher.  However, the audio
codec that they use can only do 96kHz.

That's actually really sad.  I wish they had used something with higher
ADC rate.  But it seems like even high-end audio codecs never get you
beyond 196/216 kHz - still insufficient for e.g. GSM.
