ADF4001BCP集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

ADF4001BCP属于集成电路（IC）的时钟发生器PLL频率合成器。由亚德诺半导体技术有限公司制造生产的ADF4001BCP时钟发生器，PLL，频率合成器时钟发生器、PLL 和频率合成器集成电路 (IC) 可为逻辑器件提供参考信号的稳定定时脉冲，这些器件包括计算机、微控制器、数据通信系统和图形/视频发生器。这些集成电路可能包括缓冲器、驱动器、分频器、倍频器、多路复用器、合成器、扇出分配器和预分频器。

GENERAL DESCRIPTION

The ADF4001 clock generator can be used to implement clock sources for PLLs that require very low noise, stable reference signals. It consists of a low noise digital PFD (phase frequency detector), a precision charge pump, a programmable reference divider, and a programmable 13-bit N counter. In addition, the 14-bit reference counter (R counter) allows selectable REFIN frequencies at the PFD input. A complete PLL (phase-locked loop) can be implemented if the synthesizer is used with an external loop filter and VCO (voltage controlled oscillator) or VCXO (voltage controlled crystal oscillator). The N minimum value of 1 allows flexibility in clock generation.
