LMX2594: Guidelines for using IBIS model

Part Number: LMX2594

Is there a way to adjust output power setting for simulations running in HyperLynx?

If not, what setting does the IBIS model default to (RESET = 31)?

Thanks

Dear Ken,

It is my understanding that the IBIS models would have been done to correspond to power level 31.

Regards, Simon.

Hi Simon,

Has the IBIS model for LMX2594 at the TI website,

www.ti.com/.../toolssoftware,

dated June 06 2017 been verified? The differential pin assignment for RFOUTB and RFOUTB* is reversed

18 RFOUTB RFOUT 0.04055 0.82255n 0.18102p
19 RFOUTB* RFOUT 0.04205 0.86548n 0.18126p

Hi Hai,
This IBIS model is for signal integrity simulation (better for digital control pins), didn't target for RFout 15GHz signal simulation.

Shawn,

The IBIS model does have information on the inductance and capacitance on this pin, but is not very detailed. I am going to mail you a doccument that has a great many more details.

Dean
