AWR2243: CSI2 data timing

Hi Experts,

The figure is from the datasheet, "Figure 9-4. CSI-2 Transmission Format". We would like to know the timing in the red circle.

Best regards,

Hello Ken,

The exact delay from last ADC sample to start of CSI transfer depends on the ADC sampling rate configured. Its typically around 4 - 4.5 usec.

Hello Vivek,

Thank you for your response. Let me double check. Do you mean both timings in red circles are around 4~4.5usec?

Regards,

Ken

Hello Ken,

The LS short packet starts 4- 4.5 usec after the chirp data is available. The frame start packet timing is not know. It will be available before the first chirp data is sent out.

Vivek
