iwr1443平台的adc采样率最小能设为多少?

Other Parts Discussed in Thread: IWR6843

    你好,

    程序中注释可设置的adc采样率范围是2Msps~37.5Msps,不能比2Msps更低了吗??

  • 你好,

    是的。在ti\mmwave_dfp_01_02_05_01\docs\mmWave-Radar-Interface-Control.pdf里,你可以找到下面的内容:

    PF DIGITAL OUTPUT SAMPLING RATE
    2 ADC Sampling rate for this profile is encoded in 2 bytes (16 bit unsigned number)
    1 LSB = 1 ksps
    Valid range:
    xWR1xxx and IWR6843 devices: 2000 to 37500 (Max 15MHz IF bandwidth)
