As I understand it, you are looking for the PMA latency information for A10 devices. As I search through the user guide and datasheet, seems like there is no specific information on this. As a workaround, it is recommended for you to run through simulation to estimate your latency for your specific XCVR configuration. Sorry for the inconvenience.
I believe the initial inquiry has been addressed. This thread will be transitioned to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you.
