2.5.1 Host Board Connectors(J4, J5)

The primary connector set on the MMWAVCAS-RF-EVM is the host board connector #1 (J4) and host board connector #2 (J5). These connectors are each implemeted with a Hirose FX23-120P-0.5SV15 Header. Connector #1 pinout containss all of the reset, boot, digital control and CSI2.0 data paths forAWRx #1 and AWRx #2. Connector #2 pinout contains the same for AWRx #3 and AWRx #4. Both connectors share a common 5.0 V power and GND return path. Primary power to the MMWCAS-RF-EVM is expected to be provided from a compatible host board through these connectors.

WARNING

It is required that any attached host board provide 5.0 V power conditioning. No 5.0 V power rail protection exists on the MMWAVCAS-RF-EVM design itself. The attached host board is expected to provide reverse polarity protectionand turn-on/off transient suppression. This is especially import to note when testing in an automotive alternator/battery powered system. The MMWAVCAS-DSP-EVM host board includes an automotive 12 V input supply rail for this purpose.
