LMX2594: How to align RFoutA and AFoutB when channel divider = 2 at category 3

Hello,

My customer would like to align RFoutA and RFoutB by SYNC pin.

OSCin, desired RFoutA and RFoutB are as follows.

OSCin = 61.44MHz

RFoutA = RFoutB = 5893.08MHz.

According to Figure 27 of the datasheet, this condition is category 3.

Then, they are stuck at datasheet 7.2.10.3-3. “Determine the value of IncludeDivide:”.

Since desired RFoutA/B = 5893.08MHz, channel divider is 2. But if IncludedDivide=4, VCO frequency gets >20GHz.

So, is it impossible to align RFoutA and RFoutB by SYNC pin in my customer case?

Any workarounds?

Oe, do they have to generate OSCin frequency of which RFoutA/B is integer multiple using anther PLL device prior to LMX2594?
