Very Low Phase Noise Synthesiser Divider

Zarlink Semiconductor Inc 

SP8400

Available division ratio

All division ratios of 64 to 4103 (Definition 1) will return

the divider to the same internal state at the end of the count

and hence these are the only divisional ratios to be used for

fractional–N synthesiser application.

All division ratios of 56 to 4103 are available for general

division purposes. Additional division ratios available for

general division are:-
