how to connect ADC

hello,

      there is a ADC with 14bit/80Msps, and the data from the ADC should be carried into the DSP. how to connect the DSP and the ADC. I know there is UPP interface in some devices, but the UPP supported only 16bit/75Mhz. any other interface/device could be used in this case?

      thanks!

    Hi Lin,

    Could you please provide DSP part in which you wanted interface ADC?

    Thanks.

    Hello,

          in general, I want to use Keystone DSP, whatever the part number. in fact, I am choosing one DSP part that support the case.

          by the way, the EMIF interface support such case if use FIFO? thanks!

    The data rate you are describing is very high. The EMIF16 interface was not designed for high speed data transfer and can't support those rates. I don't think that the UPP, McBSP or TSIP interfaces would be sufficient either.  You best approach would be to use one of the serdes interfaces such as SRIO. You would need an FPGA to interface with the ADC and communicate with the SRIO interface on the DSP.
