CCS/AWR1642: How is the sampled data converted to 16-bit data?

Hi,

The output of the Digital Front End is 16-bit and can be formatted to 12,14 or 16 bit.

Thank you
Cesar

Hi Cesar，

Thank you for your reply.

So how do I format this so that I can move the ADC data out 4 bits to the right?

Is there any documentation on the rf front-end output data format?

Thank you

Hi,

The front end can be configured to provide 12bit, 14bit or 16bit ADC data

What format would you like to use?

I am not clear why you need to modify the ADC data

Thank you
Cesar

Hi Cesar，

 I used the 16bit adc data output to perform 1D FFT calculation by using DSP_fft16x16().

However, I found that when the adc data exceeded 8192, the 1D result of DSP_fft16x16() would produce an abnormal spike.

Therefore, I want to format the 12bits data of the 16bit adc data for calculation.

So how does the rf front-end convert 12bits of ADC data into 16bits or 14bits of ADC data output?

Thank you
