3.1.1 General The synthesizer section includes the prescaler IC (U601), the synthesizer IC (U602), and the reference oscillator (U600). The prescaler and the synthesizer chips are completely controlled by the serial data bus. The prescaler IC provides the following: ⢠Multi-dual modulus prescaler ⢠5-V regulator ⢠Super filter 8.6-V regulator ⢠Fixed divide-by-8 circuit for the reference oscillator ⢠Programmable divide-by-N and charge pump phase detector to support the second injection VCO The synthesizer IC provides: ⢠Reference divider ⢠Phase modulator ⢠Dual-bandwidth adaptive filter ⢠Ramp generator ⢠Sample-and-hold phase detector ⢠Programmable loop divider ⢠Auxiliary output bits for system control
