[Discuss-gnuradio] TVRX IF frequency

[melanio]

In data sheet of Microtune 4937 DI5, the IF frequency of a tuner comes out to 5.75MHz.

But according to it directly measures(pin17,18) with spectrum analyzer, the IF frequency is 44MHz.

Moreover, DDC values comes out to -20M if ‘usrp_fft.py’ is carried out.

So the ADC is 64MSPS, I don’t know why DDC is -20M and why IF frequency is 44MHz.. is it possible figure?
