2.2 AWR2188 Radar Configuration

The AWR2188 supports CSI configuration modes for RAW8, RAW12, and RAW14. For any given frame, all data must use the same configuration. When transmitting data for a single chirp, the placement of line start and line end markers can be flexibly configured. Typically, a Horizontal Start (HS) marker is placed at the beginning of a chirp, and a Horizontal End (HE) marker at the end of a chirp. When sampling at 16-bit resolution, ADC data shall be transmitted from CSI-2 in RAW8 format; when sampling at 12-bit resolution, data shall be transmitted in RAW12 format. The AWR2188 supports configuration of a CSI test pattern generator for rapid validation of CSI packet content.
