USB Demodulator usin tm4c123 development board

[AhmedGalal]

In advance I'm not embedded systems engineer , so

I have a MAX2112 DVB-S2 tuner and its circuit , its output are i+ , i- , q+ , q- , now I should take these outputs and the i2c two wires to demodulator , then to DSP chip , but in fact i'm interested in Software Defined Radio so taking these outputs to something in between the pc host and the Tuner(MAX2112 circuit) ,so I use TI tm4c123 it has many analog inputs and ADC pins ----------- my question------- is that configuration right for upstreaming the demodulated signal on the USB 2.0 port to the host pc ?

thanks in advance .

as long as you have i+ and i-. So you need to have differential input pins to digitize these inphase/quadrature signals correctly. In addition, you should have a usb module in the TI tm4c123 in order to communicate with the pc or an ordinary uart module with ftdi chip to interface with the pc.
