      Dear K**bleep**ij,

      If it is supported does Intel have any Documenation on this ?

      What about a Quartus design e.g. ?

      Thank you for all your help once again

      Bests regards

    Hi,

    Support speed range of Cyclone V GX(622Mbps ~ 3.125Gbps) / GT (622Mbps ~ 5.0Gbps).

    For #1, Minimum bit rate is 622MHz (max run length is 200 UI). You can refer to CV Datasheet.

    https://www.intel.com/content/www/us/en/docs/programmable/683801/current/transceiver-specifications-for-cyclone.html

    For #2, It should be totally balanced. I don't know exact allowable running disparity characteristics, but it should be within +/- 2or3 (<8B10B). You can find the limit by the web search like below.

    For #3, Maybe it is AC-coupled configuration, so data toggling is needed to keep balannced signal. Same as #2 it should be DC-balance signal needed for AC-coupling.

    Hope this will clarify.

    Thank you,

      Dear K**bleep**ij Goel,

      Do you have any design examples that could test this on a Cyclone V GT development board ? We specifically need a design that will enable us to transmit \ receive between a NIOS and an external optical transceiver ?

      Best regards
