PLL频率合成器

ADF4107频率合成器在无线接收机和发射机的上变频和下变频部分中，可用来实现本振。它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（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)。其带宽极高，因此许多高频系统可以省去倍频器，从而简化系统架构并降低成本。 • 带宽：7.0 GHz\n\n• 2.7 V至3.3 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\n\n• 可编程双模预分频器：8/9、16/17、32/33、64/65;
