Other Parts Discussed in Thread: EVMK2GX
Hello,
We would like to perform beamforming operations on EVMK2GX using analog microphones, so we need an ADC inbetween. On Voice Processing Tools and Software for K2G and C5517 Designs, we saw that 2 PCM1864 ADCs were being used. We were wondering how two ADCs can be made to sample and give output simultaneously since this will be crucial in our microphone array application. Also, could you explain the hardware necessary? Would it be as simple as connecting the output of mic to ADC and connecting ADC's relevant output to DSP or is there an additional circuitry involved?
Moreover, is 192 kHz max sampling rate for this ADC per channel?
Thank you.
Best regards,
Sueda
