ADC >500MSPS parallel LVDS interfacing with DSP

Ayman Hendawy

Hi,

I need to understand how to interface the high sampling rate ADCs >500MSPS, with DSP cores over parallel LVDS, how to do so, how to interface parallel lvds from dsp, what requirement in dsp should I focus on, any details to understand pls.

I selected parallel lvds as I see that the alternate option would be jesd204b, which found in fpga, and keystone II high priced cores.

Thanks

Hi Ayman

There are a few DSP products with LVDS parallel interfaces, but none that I am aware of can operate at 500 MSPS or even 250 MSPS.

The conventional approach is to interface the ADC LVDS outputs to an FPGA with built-in DSP features.

Best regards,
