9.4.1 ADC Data Format Over CSI2 Interface

The IWR6243 device uses MIPI D-PHY / CSI2-based format to transfer the raw ADC samples to the external MCU. This is shown in #X3538.

  • Supports four data lanes
  • CSI-2 data rate scalable from 150 Mbps to 600 Mbps per lane
  • Virtual channel based
  • CRC generation

The data payload is constructed with the following three types of information:

  • Chirp profile information
  • The actual chirp number
  • ADC data corresponding to chirps of all four channels
    • Interleaved fashion
  • Chirp quality data (configurable)

The payload is then split across the four physical data lanes and transmitted to the receiving D-PHY. The data packet packing format is shown in #X2495
