It seems the chip does not output the raw I and Q values... It means there
is nothing to do with it except watching tv, exactly the converse of
existing tuners ;-)

I just received a Product Announcement from SILICON
LABS. There new TV
Tuner Chip, the Si2177, appears to be able to demodulate Analog TV directly
on the chip without software. If I am not mistaken, this function is a new
feature in TV Tuner Chips, which may provide a much better SDR than current
TV Tuner Chip Dongles, especially when it comes to noise performance. It
also eliminates almost all external components. RF Input Frequency Range -
42 to 870 MHz
