, and a maximum division ratio of 4103. Special circuit techniques have been used to reduce the phase noise considerably.
synthesiser divider The divider is based on a divide by 8/9 modulus prescaler, and a 12 stage control counter. This gives minimum fractional
– N division ratio of 64 (56 for general division), and a maximum division ratio of 4103. Th.
