AWR1243: CSI2 mapping of Radar frames

Part Number: AWR1243


Hi,

We want to convert RAW ADC data coming out through CSI2 interface in to some different interface format.

For this we want to configure CSI2 receiver to accept MIPI CSI2 data coming out of 1243 [AWR1243BOOST].

AWR1243 configuration:

  • CSI2 data rate - 600Mbps @ 4 output lanes
  • No. of FFT points - 1024
  • No. of Chirps - 512
  • No. of Rx - 4
  • ADC bits - 16 [Complex]

CSI2 Receiver requires input configuration as per image sensor and needs following info:

  • THS-Prepare: 46.67ns min. [We calculated based on datasheet]
  • THS-Zero : 115ns min. [We calculated based on datasheet]
  • CSI clock - 300MHz [DDR of 600Mbps]
  • Data format : RAW8 [ADC 16-bits]
  • H-Active: ??
  • H-blanking - ??
  • V-Active - ??
  • V-blanking - ??
  • Frame rate - ??

Please help in understanding the mapping of RADAR frames in terms of these values to configure CSI2 receiver.

Your quick response will be highly appreciated.

Regards,

ND
