LMX2594: Only 1 Single Ended Output use of RFoutAP

arye nudelman

Part Number: LMX2594

Hi,

If i only want to use a single output (with single ended configuration) for example only from RFoutAP, what should i do with all other outputs ?

can i leave them open? didn't find any note regarding this question in the documents, did i missed something?

Tnx,

Arye

Hi Arye,

The M pin should have the same pull-up as the P pin and then AC-couple to a 50Ω shunt.

For RFoutB, you can leave it open and disabled it through register programming.

this i did thanks

as i see below i need to set RFoutB to high impedance right?

if not these are the registers could you please assist by directing me to the right registers?
