小数N分频频率合成器

ADF4153是一款小数N分频频率合成器，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。它由低噪声数字鉴频鉴相器(PFD)、精密电荷泵和可编程参考分频器组成。该器件内置一个Σ-Δ型小数插值器，能够实现可编程小数N分频。INT、FRAC和MOD寄存器可构成一个总N分频器(N = (INT + (FRAC/MOD)))。此外，4位参考分频器（R计数器）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 简单的三线式接口控制所有片内寄存器。该器件采用2.7 V至3.3 V电源供电，不 • RF带宽达4 GHz\n• 2.7 V至3.3 V电源供电\n• 独立的电荷泵电源VP可提供扩展的调谐电压 \n• Y版本：-40°C至+125°C\n• 可编程小数模数\n• 可编程电荷泵电流;
