双通道、整数N分频0.5 GHz /1.2 GHz PLL

ADF4216/ADF4217/ADF4218均为双通道频率合成器，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。这些器件可以为射频(RF)和中频(IF)部分提供LO。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（6位）、B（11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)。 • ADF4216: 550 MHz/1.2 GHz\n\n• ADF4217: 550 MHz/2.0 GHz\n\n• ADF4218: 550 MHz/2.5 GHz\n\n• 2.7 V至5.5 V电源供电;
