ADF4350 - RF performance enquiry?

Dear Sir,

 

1) For the ADF4350, is there a fixed phase difference between RF out A and RF out B?

 

2) Secondly, the datasheet shown that the quantization noise of the SDM is depends on th2e particular phase word which can be varied to optimize the fractional spurs level on any partificular frequency. How can I determine the value of phase word to achieve that spur optimization for let's say 2.37-2.42GHz.

 

Thanks,

KL
