    • A voltage control signal at a voltage control signal input terminal is used to adjust an output frequency of an oscillator circuit. The voltage level of the voltage control signal is converted in a one-bit analog-to-digital converter (ADC) to a digital output indicative of the voltage level. Successive digital representations of the voltage level of the voltage control signal are upsampled to generate upsampled blocks of data. A dither circuit inserts a digital dither in the upsampled blocks of data to generate dithered upsampled data, which is used to generate a control signal for a feedback divider of a phase-locked loop circuit and thereby adjust the output frequency.
    • 电压控制信号输入端的电压控制信号用于调整振荡电路的输出频率。 电压控制信号的电压电平在一位模数转换器(ADC)中转换为指示电压电平的数字输出。 电压控制信号的电压电平的连续数字表示被上采样以产生上采样的数据块。 抖动电路在上采样数据块中插入数字抖动以产生抖动上采样数据,用于产生用于锁相环电路的反馈分频器的控制信号,从而调节输出频率。
