AFE7950: Follow-up on previous question - strange behaviour in RX AMI-IBIS model

Magdalena Richardson

Part Number: AFE7950

Hello, please see linked question https://e2e.ti.com/support/rf-microwave-group/rf-microwave/f/rf-microwave-forum/1176505/afe7950-ibis-ami-model-for-serdes-rx-has-peculiar-behaviour-in-hyperlynx-vx-2-11 - question was locked, however issue is ongoing.

Summary: RX IBIS-AMI model exhibits strange behaviour when running SerDes simulations, even when used with the AFE7950 TX driver, a Xilinx driver, or a generic driver. The problem does not improve when a channel is added, or when the channel is completely removed.

Has this problem occurred before? Does this model act normally in Hyperlynx for your in-house simulations?

Thank you.

Hi Magdalena,

We have set this up in our lab and we face the same issue. We are working with our design team to figure out if the issue is with the model or if we are missing something in the simulation.

I should have an answer by the 24th of March.

Regards,

David Chaparro

Hi Magdalena,

I wanted to reach out and let you know that the latest version of the IBIS models have been loaded in the AFE79xx secure folder.
