Hello,
You can go to below link for some guidelines to avoid loss.
Usually you will need a re-driver for PCB traces longer than 6", we have both USB3.0 and SATA re-drivers, please look at below links.
We don't have Spice model I can send you a ibis model.
Regards

Hi Elias,

Thank you for checking! Understood that no SPICE model available for this device.
I will discuss with customer.

I found the IBIS model from here.

Thanks,
