AWR2243: Questions about the CSI Data

Part Number: AWR2243

Hi Team,

i have some general questions about the CSI Data, that is being send by the AWR2243. I want to receive the signal on a external host, which is Linux based. On this host, i have to specify some characteristics of the CSI Data. For the following characteristics, i am unsure what the correct value would be:

- Active Height (in Pixels)

- Active Width (in Pixels)

- Total Height (in Pixels)

- Total Width (in Pixel)

From other posts and information online, i am assuming that the active Height and Width are the Number of Chirps and the Number of Samples * Active RX Elements. So in Case of 32 Chirps per Frame, 128 ADC Samples (Times two because of Complex Mode) and all RX enabled, active Height would be 32 and active Width would be 1024. Is my assumption correct?

If so, how can i calculate the Total Height and Width, that is present because of horizontal and vertical blanking. I need this information to calculate the Pixel Clock, which is needed by my Host Processor to correctly receive the CSI Data.

Thanks,

Tim
