单通道、整数N分频、4.0 GHz PLL，内置可编程预分频器和电荷泵

ADF4110系列频率合成器可以用来在无线接收机和发射机的上变频和下变频部分实现本振。上述器件由低噪声数字鉴频鉴相器(PFD)、精密电荷泵、可编程基准分频器、可编程A和B计数器以及双模预分频器(P/P+1)组成。A（6位）、B（13位）计数器与双模预分频器(P/P+1)配合，可实现N分频器(N = BP+A)。 \n\n 此外，14位参考分频器（R分频器）允许PFD输入端的REFIN 频率为可选值。如果频率合成器与外部环路滤波器和电压控制振荡器(VCO)一起使用，则可以实现完整的锁相环(PLL)。 所有片内寄存器均通过简单的三线式接口进行控制。这些器件采用2.7 V至5.5 • ADF4110：550 MHz\n\n• ADF4111：1.2 GHz\n\n• ADF4112：3.0 GHz\n\n• ADF4113：4.0 GHz\n\n• +2.7 V至+5.5 V电源供电\n\n• 独立的电荷泵电源(VP)可在3 V系统中提供扩展的调谐电压;
