4.3.2 Data Capturing Approach

Figure 4-2 shows the capturing approach with the DCA2000EVM.

The reference design is connected with a coax cable for data transmission to the DCA2000EVM FPD-Link deserializer daughter card. This daughter card includes the DS90UB9724S-Q1 FPD-Link deserializer. The daughter card connects the CSI-2 from the deserializer to the DCA2000EVM through Samtec high-speed connectors. The DCA2000EVM stores the radar data from the AWR2188 on an attached SSD and is able to transmit the recorded data to a PC through a standard Ethernet interface.
