SI5344: Out of Frequency

objective: to understand how OOF works on input frequency

 

By using ClockBuilder Pro, we just need to set the input freq at step 7,

but which register is actually being set that allow si5344 know what is the target input freq? 

 

which register to set in order to tell si5344 know the target input freq to check is 10MHz( etc)?

 

what is the relationship of "OOF0_DIV_SEL" to input frequency?

 

how is the value in this register OOF0_RATIO_REF being calculated?

 

any block diagram to explain the above question?

 

please advise.

 

Thanks.
