Setting True LVDS input and output in MAX10

I am creating a new board based on MAX10 FPGA, so I started Pin Planning Project. As read in MAX10 docs, bank 3 and 4 support True LVDS output, but when I try to set LVDS protocol to the pins in b...

Hello AminT_Intel,

I know I can use Emulated protocols, my question is about the true ones, shouldn't MAX10 support them ? Why I can't use them?

I want to lower the number of resistors on the board and reach faster signals speeds since True protocols capable of handling faster clocks and data rates.

Hello,

There are requirement to do that and you have to follow the right specification (like example the right I/O standard) to be able to do that. Please refer our to our document (Intel® MAX® 10 FPGA Device Datasheet) on your design.

Thank you

    Hello AminT_Intel,

    Mr. AminT_Intel, the device supports True LVDS as stated in (Intel® MAX® 10 FPGA Device Datasheet), so why I can't use LVDS in these bank3 and 4 pins ?!

    Please if are willing to help me, give me a good answer, not a general statement.

      Hello,

      True LVDS input buffer is supported in all I/O banks

      True LVDS output buffer is only supported on bottom I/O banks.

      Please refer to Intel® MAX® 10 High-Speed LVDS I/O User Guide for detailed explanation.

      Thank you.
