Experiment with S-10 Transceiver IO Terminations

Hi, I am performing some experiment with S-10 SoC Dev kit (L-tile). I am using FMC loopback cards to check the behavior of SERDES so as to use for my final requirement. My goal is to connect a dev...

Hi,

Regarding the slew rate control settings, as I understand it from the user guide, 0 = slowest and 5 = fastest. There seems to be no specific specs in term of seconds in the user guide.

Thank you.

Best regards,

Hi,

I carried out the experiment with TX& RX termination set to 85 ohm and Slew rate control = 5. With this I am seeing the eye opening.

attached the snapshot of the same. Eye is captured with PRBS7. Also, I checked the BER for PRBS31 by transmitting around 10^12 bits, but BER remained 0 in the TTK.

With regards,
