GTY transceiver in UltraScale+

Is there any roadmap to get the GTY 32.75Gb/s Transceivers in the UltraScale+ KU5P A676 package to work at 32.750 Gbps?  Do we know why it doesn't?

Thank you!

Re: GTY transceiver in UltraScale+

Hello @tooslow666 

KUS_plus_GTY_32G.png
I can set 32.75Gbps on Transceiver wizard. (see above)
I am also using the device model you told me above. (xcku5p-ffva676-3-e (active))
So, I donot see any issue for 32.75Gbps usecase.

Are you using speed grade:-2 or -1 device ?

Thanks & regards
Leo

Re: GTY transceiver in UltraScale+

Thanks for the response, but I see in the spec sheet at page 7, at the bottom (https://www.xilinx.com/support/documentation/data_sheets/ds890-ultrascale-overview.pdf) that :

GTY transceiver line rates are package limited: SFVB784 to 12.5Gb/s; FFVA676, FFVD900, and FFVA1156 to 16.3Gb/s.

Regardless of the speed grade, the more important is to have 32.75Gb/s transceivers and the 676 package.

Re: GTY transceiver in UltraScale+

Hello @tooslow666 

I believe you are correct. The package of your device model limits the GTY line rate to 16.3Gbps.
Please consider choosing a different package (B676 for example).
