TDC7201: TDC7201

Part Number: TDC7201

TDC7201测量設置多次 STOP,要怎麼使用其他STOP所計算出來的值,是否可以舉例說明 

  • 您好,

    在 TDC7201 数据表 7.4.2 Measurement Modes有2种测量模式的计算方法。另外,TI不建议使用测量模式1测量大于2000 ns的时间,因为这会降低测量精度。

  • 7.4.4的章節,stop有五次,請問有應用的範例可以參考嗎。

  • 非常抱歉,这个我没找到相应的计算示例。但是这个仅是改变了 CLOCK_COUNTn值:

    The CLOCK_COUNTn registers should be right shifted by the log2(AVG_CYCLES) before calculating the TOF. For example, if using the multi-cycle averaging mode, Equation 2 should be rewritten as: TOFn = normLSB [TDCx_TIME1 - TDCx_TIME(n+1)] + [TDCx_CLOCK_COUNTn >> log 2 (AVG_CYCLES)] x [CLOCKperiod]
