Interfacing with lots of ADCs using LVDS

I need to process up to 24 ADCs, each running at 5-10MSPS. Each ADC needs to have 12 bit resolution, and the ADCs are spread over 3 PCBs. The AD9220ARS would do as a good economical 12bit ADC, but interconnecting 24 of them looks ugly. Quad or octal devices might be a way forward, but has anyone tried using LVDS interfaces to get the sheer number of interconnects down?

  • Hi,

    We use a Virtex4 FPGA from Xilinx to capture the data of the AD9637.  These octal ADCs are used in systems where the channel count can be very high, such as 256 channel ultrasound systems, and FPGA or dedicated ASICs are the usual solution.

    Good luck with your design,
