LMX2615-SP: Drive Strength for IBIS Model?

Joseph Sanchez

Part Number: LMX2615-SP

Tool/software:

Hi, this part has a register that can control the drive strength of the RF outputs. Is there a way to adjust this drive strength in the IBIS model?

Hi Joseph,

Yes, this is supported.

I think this is for the MUXOUT or pin 32 of the device. I'm talking about the RFOUT pins.

opps....

No, IBIS did not model RFout power setting.

Is it something that can be added?

Hi Joseph,

I need to check if this is doable. What is the reason for this option? What are you trying to simulate? You know, IBIS is not intended for RF signal sim.

Well it seems to be failing a batch simulation in Hyperlynx. It could also be the receiver I'm using but I wanted to see if changing the drive strength helped.

Hi Joseph,

It might also be due to the IBIS model as it is not tailor-made to support RF frequency.
