Ultrascale LVDS_25 HR to Ultrascale+ LVDS HP

Jump to solution

Hi,

I am working on a project where I need to communicate between two FPGAs.

The transmitter is on an Ultrascale HR Bank and uses LVDS_25. The receiver is on an Ultrascale+ HP Bank and uses LVDS (1.8V).

Is it possible to connect the two directly together (using a proper cable)? From UG571(v1.9), Figure 1-82 (attached) seems to imply that LVDS and LVDS_25 are interchangeable on both transmitter and receiver. Can someone please confirm this? As the compatibility is not specifically stated.

Thanks in advance.  LVDS.PNGUG571 - Figure 1-82

Hi @kg1,

If Transmitter LVDS_25  Vodiff and Vocm specs are within range of the Vidiff and Vicm of LVDS_18 of Receiver, you are good to go.

Please refer this https://www.xilinx.com/support/answers/43989.html for more information.
