LMX2820: Output Divider Configuration

Part Number: LMX2820


Hello 

In the datasheet two output dividers appear one per RFoutput:

But on page 19 we have one divider common for both outputs:

Which one the correct? 

We need exact phase for both RF Outputs, preferred to use the same divider for both outputs, so figure 7-1 is preferable.  

Thanks

    Hi There,

    There is only one divider, but the divider is constructed with several blocks, Both output can tap the signal out from one of the blocks, as a result, they can have different division. 

    If bout output frequency is identical, both signals come from the same block output so their phases are identical.
