xapp224 clarification

Hi!

 

I am designing a data recovery following xapp224 for spartan-6 but I could not understand the data valid DV (11, 00, 01) which I think for the bit lost/duplicated problem.

 

can anyone explain it to me please,

just to clarify the XAPP if for Virtex and so not supported on spartan-6. It sounds like you are using the principles within it.

the DV signals look like a single bit so if it high then data is valid and if low it should be ignored - invalid.
