SP8861 13GHz Low Power Single-Chip Frequency Synthesiser Datasheet

SP8861 13GHz Low Power Single-Chip Frequency Synthesiser

Prescaler and AM Counter The programmable divider chain is of AM counter design and therefore contains a dual modulus front end prescaler, an A counter which controls the dual modulus ratio and an M counter which controls the bulk multi-modulus division. A programmable divider of this type has a division ratio of MN1A and a minimum integer steppable division.
