TDC1000触发时序问题

您好，这个时间间隔在datasheet page26的8.4.5.2 TX/RX Measurement Sequencing and Timing有介绍，即Note A 这部分的时间T=3T0+2T1或者T=3T0+3T1. 举例ƒCLKIN = 8 MHz，分频系数TX_FREQ_DIV 为8， 那么周期=1/8Mhz=125ns
, T1=1uS, 因此START和触发Triger之间的时间差为3*125ns+2*1us=2.375uS或者3*125ns+3*1us=3.375us。


During resynchronization, the trigger and START edges are aligned to the negative edge of the external clock.
The time between trigger and START is equal to 3 T0 periods plus 2 or 3 T1 periods, depending on the phase
between the received trigger pulse and the external clock. For example, if ƒCLKIN = 8 MHz and TX_FREQ_DIV =
0h2 (divide-by-8), the period T0 is 125 ns and the period T1 is 1 µs, resulting in a time of 2.375 µs or 3.375 µs
between the received trigger signal and the generated START pulse.
