IWR6843AOP: Difference between SYNC_OUT and FRAME_START signals

Riccardo Repetto

Part Number: IWR6843AOP

Tool/software:

Hello,

Can you explain to me the difference between the SYNC_OUT signal (that can be mapped to K3, L3, M3, U12) and the FRAME_START one (that can be mapped to K3, V10, V13 pin) in the IWR6843AoP devices?

Thanks in advance,

Riccardo

Hi Riccardo,

FRAME_START signal gives a GPIO toggle for every frame starting in the FMCW chirping profile. This signal can be used for development purposes to synchronize the chirp start at each frame.

SYNC_OUT signal can be used for hardware triggers in order to synchronize with other devices.

Thanks,

Swarnendu
