Over sampling on Intel Stratix 10 Gx transceiver SI development kit

According to "Intel® Stratix® 10 GX/SX Device Overview" (April 8, 2021), S10 transceivers can support data rates below 1 Gbps with over sampling. I have a set of Intel S10 GX transceiver SI develo...

Hi,


Yes, It mentioned it can support data rates below 1Gbps with over sampling. That means you need to stuff extra samples before feeding.


And to get 1.6Gbps or 6.4Gbps, it is already above 1Gbps. Why do you need over sampling?


Can you please more specific and clear with your query.

Also, please mention which OS , Quartus version and device OPN you are using?



Thank you

Hi Kshitij,

Here is the link to the transceiver SI development kit I am using - https://www.intel.com/content/www/us/en/products/details/fpga/development-kits/stratix/10-gx-signal-integrity.html

I am using Windows 10 and Quartus Pro 18.1.

Please let me elaborate my question a bit more...I send 28.25Gbps over transmitter on a transceiver on the development kit and receive 1.6Gbps over the receiver on the same transceiver. In this case, reference clock (Y2) will be 644.35MHz. My question - will the receiving path take data in 1.6Gbps? If not, how to (as S10 support 1.6Gbps with oversampling)?

Thank you,

Jun
