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

Any News ?

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 ?
