LMH1982 TOF 输出与输入VS对齐疑问

Kailyn Chen ，你好！

感谢你的答复，你说的问题点我会去确认。

另外我想再确认下这样的情况除了以上硬件的影响之外，与LMH1982软件的配置会有关系吗？

以下是数据手册的第31页描述初始化顺序时，特别强调了“EN_TOF_RST” “TOF_INIT” 两个BIT位的设置顺序，

红色字体标注的时间要求，如果没有严格执行，会导致我出现我提问的问题吗？ 还是说只会导致时钟的抖动变大？

During the output frame immediately prior to the frame the initialization is to occur:
1. Set EN_TOF_RST = 1(register 0Ah) to enable output alignment mode.
2. Toggle TOF_INIT (register 0Ah) from 0 to 1 to reset the internal counters. On the next frame, the output
clock and TOF pulse will be initialized (aligned) to the reference frame with line offset programmed to
TOF_OFFSET.
3. Immediately after the initialization and before the next output frame occurs, clear EN_TOF_RST and
TOF_INIT to 0. Otherwise, the output clock will be continually aligned on every output frame while
EN_TOF_RST = 1. Continual alignment which may cause excessive jitter on the output clock (from PLL 2, 3,
or 4) due to slight differences in the delay paths of the internal logic. This occurrence of excessive clock jitter
can be avoided by disabling output alignment mode (EN_TOF_RST = 0) immediately after the initialization
sequence.

您好，合理的初始化顺序是芯片正常工作的必要条件，我的建议是严格按照这个初始化的流程来，然后一步步排除问题的可能性出现在哪里。

Kailyn Chen，你好！

我目前是有严格按照以上步骤执行的，规格书第2步描述的“On the next frame, the output clock and TOF pulse will be initialized”，以及第3步描述在下一帧来之前要将该这两个标志复位， 我理解为下图的顺序以及时间要求，不知道正确与否？ 请帮忙确认一下
