Hi CC chen, thank you for the amazing tutorial for SERDES. I have one request for you to make some video on how to tune CTLE, REMOTE TX and VGA gains to minimize the ISI . Based on pulse response or frequency response. I tried to use pulse respones as tool to minimize ISI but when I check PRBS simulation result the it do not match with pulse response.
What are the practical pros and cons of impulse response simulation vs numerically calculating the difference between two step response (a positive and negative step response) simulations?
Hi Joseph, Thanks for the good questions. I have comments below. What are the practical pros and cons of impulse response simulation vs numerically calculating the difference between two step response (a positive and negative step response) simulations? [CC] Are you asking about the correlation between the single-shot align with the two step responses? If yes, my understanding is that it should be equivalent if both responses don't saturate the system, which only assumes the passive elements of the lossy channel. :) Thanks, CC

Hi Greywhittef,
Thanks for the good suggestions and I'll do it. :)
Thanks,

Closed eye is very important for measuring super high Speed data analysis 🤔
Hi Lab_mangement, thanks for your feedback. Yes, the eys is is very important for measuring super high Speed data analysis. :)
