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.
