AM5K2E02: PCIe clock IBIS model

Part Number: AM5K2E02

Hello,

The IBIS model for the AM5K2E02 processor does not have a model for the PCIe clock inputs.

Are there any plans to release a model?

Is there a equalivalent model from another device that i can use?

Hi,

As far as I know this is not publicly available yet. See this thread:

Bob,

Are you asking about The K2E IBIS model or the IBIS-AMI model for the KeyStone-II SERDES interfaces? Both are available on the AM5K2E02 product page (http://www.ti.com/product/AM5K2E02/toolssoftware#devtools).

I'm asking about the IBIS model the AMI model doesn't include the reference clock just the RX/TX.

The current IBIS model has a NC model with no data for the PCIe clock pins but the datasheet says there is a termination on the processor. I would like to simulate this.

Bob,

The SERDES clock inputs contain an internal 100-ohm differential termination. However, it is not active until the SERDES module is activated and configured by software.

Since this clock input is part of the SERDES IP block, it should be modeled within the IBIS-AMI model. However, as you indicated, it is not in the IBIS-AMI model. There is no plan to update the IBIS-AMI model. It is available as-is. You will need to model it simply as the 100-ohm differential load.
