Part Number: LMX2594

Hi
LMX2594

Is it possible to invert the phase of RFoutAx and RFoutBx by 180degrees?
If possible, please tell me how to set it.

Additional information

I am referring to the data sheet page25 "Phase Adjust".
Is it possible to set Phase-Shift in degrees=180 by changing MASH_SEED?
※In addition to this setting, please tell me if there is a method to invert the phase.

Below the frequency is set.
fVCO= 8680.413MHz
RFout=90.42096875MHz

best regards

Hi cafain,

No, the phase of channel A and B are always aligned because their sources are identical.

Hi, Noel-san

RFoutAx and RFoutBx have the same phase,
At the same time can you invert the phase of both outputs by 180 degrees?

best regards

Hi cafain,

Yes, this is possible. Section 7.3.11 in the datasheet has the details.
