prescaler phase noise degradation over the full RF operating range. The comparison frequency is obtained either from an on-chip crystal controlled oscillator, or from an external source. The oscillator frequency, fREF, or phase comparator frequency, fCOMP, can be switched to the REF/ COMP output providing a reference for a second frequency synthesiser. The synthesiser is controlled via an 12C bus and is fast mode compliant. ……
