Transceiver speed grades

Hi, Targeting to use Stratix 10 SX SoC FPGA for an application which includes transceiver working at ~22Gbps per channel. Such 4 to 8 lanes (both TX and Rx) may be there in use at a time. Initially...

Hi,

That's a good question. If you look at s10 SX/GX device overview datasheet and the part used in the s10 soc board(1SX280U) the X means that there are transceivers working at 28.3Gbps maximum.

GXT channels can achieve this, and GX ones can run up to 17Gbps.

In the manual of the demo board, there are 8 GXT Channels on FMCA port and 8 other GXT channels on FMCB.

I guess you will have to buy a FMC daughter card with SMA connectors for your test bench.

Also, have a look to stratix 10 datasheet, everything is explained about transceivers (E-Tile, H-Tile and L-tile)

Hope it helped,

regards,

John

Hi John,

Thank you for the info. and asking me to go through the transceiver userguide. I found the table briefing about the impact of speedgrades.
