2.14.1 RDIF Interface for Raw ADC Capture

The xWRL1432 doesn’t have LVDS I/Os, mainly to reduce the overall power consumption of the SOC. However, the DCA1000 board needs LVDS signals on the clock and data interface for raw ADC capture. For that reason CMOS to LVDS converters are used on the board as shown below. The data capture interface uses RDIF (Radar Data interface) for transferring the data between mmWave device and DCA1000 capture card. There is no change needed in the DCA1000 capture card for this purpose, however a new low power mmWave studio needs to be used for this purpose. The low power mmWave studio interprets the RDIF interface and provides a raw ADC data visualization platform for further signal processing.
