IWR1443: Delay time from SYNC_OUT input to start of frame chirp

HI Pedrhom,

Thank you for your reply.

If it is +-5ns, I think it is one cycle of the 200MHz clock. Is it correct to understand that there is no software processing such as an interrupt after receiving the SYNC_IN input until the start of the frame?

Best regards,

Hiroyuki

Hello,

No processing is done post data send until start of next frame. We have several diagrams showing the process in which a frame is sent out and what is done inbetween frames. You can find them in the mmWave SDK installation through the Doxygen documents.

Hi Pedrhom,

Thank you for your reply.

I understand that there is no processing from the time the data is sent until the start of the next frame.

I misspelled the title of the thread, but I would like to know if there is any software processing between the SYNC_IN pulse input and the start of the frame (chirp).

If the fluctuation width of the transmission delay from the SYNC_IN input is 160+-5ns, I think that the SYNC_IN pulse is processed by the hardware circuit and the frame starts without going through software processing, is this correct?

Regards,

Hiroyuki

Hi Pedrhom,

What is the situation of this question?
Please update me [us] on the current situation.
