具有可调振荡器和独立变频器和频率计数器的锁相环电路

Phase locked loop circuit with a tunable oscillator and an independent frequency converter and frequency counter
摘要：
A phase regulating arrangement or circuit is disclosed, in which, in addition to a frequency divider, which is arranged in the feedback path of the PLL and, provision is made of a further frequency counter. The frequency counter is configured to be readable and is likewise connected to the oscillator output. The frequency counter drives a control unit that selects a desired frequency band of a multiband oscillator. The phase regulating arrangement or circuit described enables very fast settling in conjunction with low phase noise and good integration possibilities.
