Greg,
I did not word my original questions well. Please consider this scenario.
Assume the customer has 8x 24 bit audio A/Ds all clocked by one master clock and sampling simultaneously. Also, assume there is no issue interfacing the A/Ds to the Sigma DSP. What is the maximum sample rate possible for the A/Ds? Can I clock them at 192 KHz? Is the SigmaDSP capable of receiving that much data (8 * 192 KHz) and processing it?
