    LVDS on PSoC5LP?

    user_366036678

      Hello,

         

       

         

      Has anyone here used LVDS on PSoC 5LP before? Or has anyone made something that could be used on PSoC 5LP to implement LVDS?

         

       

         

      It'd be great to at least have some tips.

         

       

         

      Thank you all,

          LVDS is, as you know, a low voltage differential signaling layer. Generaly used at high

             

          speed.

          You could facilitate a LV scheme using VDACs but the speed would be abhorrently

             

          slow with poor skew and CM preformance.

             

           

             

          Think about using external translator logic to implement the physical layer and SPI, then

             

          maybe you could get SPI rates over the link. But nothing like the typical 100 mbit rates

             

          one sees in LVDS.
