LMX2581 RFoutA and RFoutB relationship?

Dan LaChance

Other Parts Discussed in Thread: LMX2581

Hello TI,

My customer is using the LMX2581. Quick question.

Is the relationship between RFoutA and RFoutB deterministic and/or fixed? Specifically, can we assume they will be synchronized or have a fixed skew to each other?

Dan,

Yes, this phase relationship is deterministic, since they are both based off the same divider. We haven't done much to characterize this phase reltationship, but it is deterministic, not random.

Dean,

Thanks, this is good news that it is deterministic. Does TI have any plans to characterize it? It’d be a good spec to know the skew between the outputs, but I think the fact that it is deterministic (fixed) means it is workable for us.

Thanks,

Dan
