DataApplicationSelectionCharacteristicOverview

  

    nRF905单片无线收发器工作在433/868/915 MHzISM频段。它由一个集成的频率合成器、一个带解调器的接收器、一个功率放大器、一个晶体振荡器和一个调制器组成。

ShockBurst工作模式的特点是自动产生前导码和CRC,且可以很容易通过SPI接口进行编程和配置。低功耗1.9V3.6V,在发射功率为-10dBm时,发射电流为11mA,接收电流为12.5mA

Ø         真正的GFSK无线收发芯片,并有为低功率应用设计的ShockBurst模式

Ø         满足ETSI/FCC要求,频率切换时间<650us

Ø         极少的外部元件,无需SAW滤波器

Ø         可调整的发射功率,最高+10dBm

Ø         具体载波监听功能,当正确的数据包被接收时,有数据准备就绪信息输出

Ø         侦测接收的数据包,当地址正确时输出地址匹配信号

Ø         数据包自动重发功能,自动产生CRC和前导码
