IWR6843: Can I get Range-Doppler Heatmap or Range-Angle Heatmap by LVDS

Hi, 

     I need Heatmap information, but if I use UART Rate 921600, the frame period can not keep in 50 ms.

Is the LVDS sufficient to output heatmap during 50 ms? If it is, how can I do this or this function had been provided

in SDK demo or lab.

Thanks,
