Is it possible to adjust OUTx_PWR in the IBIS model?

Please tell me how to lower the output to simulate.

Does that mean that you can not change the output itself?
Is there a way to SI-simulate RFOUT?

Hi Hosoki,

I believe that the IBIS model is built with OUTx_PWR set to 31. Besides, simulation for output power using IBIS model wouldn't be accurate at high frequency.

Hi Hosoki-san,

We don't have any model for the high frequency RF output ports. The RF output impedance is small. If you want to have a better match with the 50ohm system, we suggest use 50ohm pull-up.
