VLYNQ to LVDS converter

Hi all,
I have faced with the following problem. I need to connect two DM6437 devices using VLYNQ interface. Problem is the distance because they are few meters far away. So my idea was to convert VLYNQ to LVDS transfer to the second device and reconvert LVDS to VLYNQ. Does anyone know is there any working hardware solution for that and if there is any other way to do the same thing.

    Hi Dejan,

    VLYNQ is just a protocol for data communication. Since signals are certainly involved, they do have a voltage standard defined for it. VLYNQ interface uses LVCMOS voltage standard for its operation.

    Refer this note - http://www.xilinx.com/products/ipcenter/DO-DI-VLYNQ.htm

    And so, you can certainly convert LVCMOS to LVDS and back using simple DC level shifting ( use single-ended  to differential converter followed by resistive network and suitable termination to define Vcm for LVDS signals)
