Freescale Xtrinsic radar chipsets are the most advanced SiGe technology on the market, consisting of a transmitter and a multi-channel receiver with an integrated phase-locked loop (PLL). Freescale's 77 GHz technology allows a device to switch between long- and short-range functionality simply by issuing a serial peripheral interface (SPI) command. This enables the same radar module to be used for multiple safety systems, such as adaptive cruise control, headway alert, collision warning and mitigation. Long-range radar, used for adaptive cruise control and lane departure warnings, has long and narrow coverage directly in front and back of the car. Short-range radar, ideal for blind spot detection, pre-crash and stop-and-go applications, monitors the car's immediate surroundings with a wide spatial view that covers shorter distances.
