8.9.2 Synchronized Frame Triggering

The AWR1443 device supports a hardware based mechanism to trigger radar frames. An external host can pulse the SYNC_IN signal to start radar frames. The typical time difference between the rising edge of the external pulse and the frame transmission on air (Tlag) is about 160 ns. There is also an additional programmable delay that the user can set to control the frame start time.
