找到一个回复,关于RF部分的相位同步,但是没有文档说明。

还有就是在reg_map文档针对0X001中有以下说明
[D3] MCS RF Enable
Only used for multi-chip synchronization. Setting this bit keeps the RF LO dividers enabled in Alert mode so that the phase relationship between multiple devices remains constant. If the bit is clear, the dividers power down in Alert mode. If this bit is clear, the respective LO dividers also turn off in FDD Independent Mode when the Rx or Tx paths are disabled. Setting this bit prevents the LO dividers from turning off. This is important if the phase relationships must remain constant through enable & disable cycles.
[D2] MCS BBPLL Enable To synchronize the BBPLLs of multiple devices, write this bit high and then provide a sync pulse to SYNC_IN.
[D1] MCS Digital Clocks Enable To synchronize the digital clocks of multiple AD9361 devices, first synchronize the BBPLLs, then write this bit high and then provide a sync pulse to the SYNC_IN pins.
[D0] MCS BB Enable Setting this bit enables the capability of baseband multi-chip digital synchronization. See also bit D1 and D2.
所以有以下问题:
1. 根据上述说明0X001 [D3]能够保持多片AD9361之间RF相位固定,但是重启上电是否相位同步有影响
2. 是否有更详细的技术说明文档
求尽快回复!!!!
