2.4.2 Secondary Radar Connector (J23)

The secondary radar connector provides all of the reset, boot, digital control, and CSI2 signals from the secondary radar device to the host (DCA2000EVM). This connector mates directly with the secondary radar connector on the DCA2000EVM. In cases where the user wishes to mate the AWR2188EVM to the DCA2000EVM using cables, the recommended part number is the HDR-241659-03-HQCD cable from Samtec.
