Differences between LVDS, true-LVDS, emulated-LVDS and mini-LVDS

Hi, I am designing a board with MAX 10 FPGA. I am really confused by all these LVDS standards. I have gone through the datasheets and user guides. But nowhere do I get any description about what ...

Hi rajesh,

true-LVDS ist just what it says, LVDS with true differential buffers. Emulated LVDS uses a pair of ordinary single-ended pins, which are driven by opposite signals. This "standard" usually needs external resistors to be (more or less) compliant to the LVDS specification. mini-LVDS seems to be just another very similar standard: http://www.ti.com/lit/an/slda007a/slda007a.pdf

As far as I know, all those differences are only relevant for drivers, the differential receivers should all be (more or less) the same.

Regards,
