产品详情资料

 距离中心频率配置小于±3500 ppm时，DCO频率是一需要重新编程的值。由于fDCO=fXTAL x RFREQ，并且fXTAL是固定的，因此更改DCO频率就像重新配置RFREQ值一样简单，如下所述：1.使用串行端口，读取当前RFREQ的值（对于所有具有20 ppm和50 ppm温度稳定性的Si571设备和Si570设备，地址为7–12；对于具有7 ppm温度稳定性，地址为13–18）。2.根据频率变化计算RFREQ的新值。3.使用串行端口，写入新的RFREQ值（温度稳定性为20ppm和50ppm的所有Si571设备和Si570设备的地址7–12；温度稳定性为7ppm的Si570器件的地址13–18）。示例：生成148.35 MHz时钟的Si570必须“实时”重新配置以生成148.5 MHz时钟。这表示+1011.122 ppm的变化，在±3500 ppm窗口内。图3.DCO频率范围f 3100•sales@skyworksinc.com•www.skyworksinc.com版次1.6•Skyworks专有信息•产品和产品信息随时可能更改，恕不另行通知•2022年3月4日此示例的典型频率配置：RFREQcurrent=0x2EBB04CE0 Fout_current=148.35 MHz Fout_new=148.50 MHz计算RFREQnew以将输出频率从148.35兆赫更改为148.5兆赫：注意：执行less than ±3500 ppm from the center frequency configuration, the DCO frequency is the only value that needs reprogramming. Since fDCO = fXTAL x RFREQ, and that fXTAL is fixed, changing the DCO frequency is as simple as reconfiguring the RFREQ value as outlined below: 1. Using the serial port, read the current RFREQ value (addresses 7–12 for all Si571 devices and Si570 devices with 20 ppm and 50 ppm temperature stability; or addresses 13–18 for Si570 devices with 7 ppm temperature stability). 2. Calculate the new value of RFREQ given the change in frequency. 3. Using the serial port, write the new RFREQ value (addresses 7–12 for all Si571 devices and Si570 devices with 20 ppm and 50 ppm temperature stability; or addresses 13–18 for Si570 devices with 7 ppm temperature stability). Example: An Si570 generating a 148.35 MHz clock must be reconfigured "on-the-fly" to generate a 148.5 MHz clock. This represents a change of +1011.122 ppm, which is well within the ±3500 ppm window.
