单通道、整数N分频1.2 GHz PLL

ADF4116/ADF4117/ADF4118均为频率合成器，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、可编程参考分频器、可编程A和B计数器以及双模预分频器(P/P+1)组成。A（5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)。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)。 \n\n 所有片内寄存器均通过简单的三线式接口进行控制。\n\n这 • ADF4116: 550 MHz \n\n• ADF4117: 1.2 GHz \n\n• ADF4118: 3.0 GHz \n\n• +2.7 V至+5.5 V电源供电 \n\n• 双模预分频器 ADF4116: 8/9 ADF4117/ADF4118: 32/33;
