ADF4007是一款高频分频器/PLL频率合成器,可用于各种通信应用。RF端工作频率可达7.5 GHz,PFD端工作频率可达120 MHz。它由低噪声数字鉴频鉴相器(PFD)、精密电荷泵和分频器/预分频器组成。分频器/预分频器值可以通过两个外部控制引脚设置为四个值中的一个(8、16、32或64)。参考分频器固定设置为2,外部REFIN频率最高可达240 MHz。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。
The ADF4007 is a high frequency divider/PLL synthesizer that can be used in a variety of communications applications. It can operate to 7.5 GHz on the RF side and to 120 MHz at the PFD. It consists of a low noise digital PFD (phase frequency detector), a precision charge pump, and a divider/prescaler. The divider/ prescaler value can be set by two external control pins to one of four values (8, 16, 32, or 64). The reference divider is permanently set to 2, allowing an external REFIN frequency of up to 240MHz.A complete PLL (phase-locked loop) can be implemented if the synthesizer is used with an external loop filter and a VCO (voltage controlled oscillator). Its very high bandwidth means that frequency doublers can be eliminated in many high frequency systems, simplifying system architecture and reducing cost.
