摘要:
ADF4360-7是一款整合了整形N合成器的压控振荡发生器(VCO)。ADF4360-7的中心频率是由外部传感器进行设定的。其允许频率范围从350MHz到1800MHz。另外可以选择使用2分频，则用户接受的射频输出信号频率范围在175MHz到900MHz。全部片内寄存器都是由一个简单的3线接口来控制的。设备操作电压范围从3.0V到3.6V并且在不使用时可以随时关闭。

Abstract:
The ADF4360-7 is an integrated integer-N synthesizer and voltage controlled oscillator (VCO). The ADF4360-7 center frequency is set by external inductors. This allows a frequency range of between 350 MHz to 1800 MHz. In addition, a divide-by-2 option is available, whereby the user receives an RF output of between 175 MHz and 900 MHz. Control of all the on-chip registers is through a simple 3-wire interface. The device operates with a power supply ranging from 3.0 V to 3.6 V and can be powered down when not in use.
