I am using Artix7 and I would like to read data from serializer IC (FIN210AC in my case) using two LVDS signals only - without the clock from the serializer IC (please see the attached image). I thought i could dynamically shift the CKSI clock phase to match the DSO. Can this be done?
So i should somehow limit the range of the phase shift to match the particular bit at ISERDES. Is this the way it should be done?

The clock source is the same. The clock source generates strobe signal at the serializer.
Do you mean i should set it to fixed delay and experiment with the tap value or should i set it to dynamic - but in this case i will not know whether it was tuned to bit0 or not?
The strobe to bit0 delay is, for instance, at 20MHz: 77ns - 90,5ns. This is quite large compared to ps range delay for each tap.
