Xtrinsic Radar Transmitter from Freescale Improves Performance, Cost and Complexity of Automotive Active Safety Systems
Industry's first 77 GHz VCO+Tx built on SiGe BiCMOS technology for automotive radar sensors improves logic and power amplifier integration
MUNICH--(BUSINESS WIRE)-- Freescale Semiconductor (NYS: FSL) today introduced the new Xtrinsic PRDTX11101 automotive radar transmitter for active safety applications, such as adaptive cruise control. The industry's first 77 GHz silicon germanium (SiGe) BiCMOS transmitter features an integrated voltage-controlled oscillator (VCO) and power amplifier for greater control, reduced system design complexity and lower system costs.
Automotive active safety applications, or advanced driver assistance systems (ADAS), are a rapidly expanding market. A recent Strategy Analyticsreport predicts that the market for ADAS, including radar applications, will reach nearly $15 billion by 2019. These are systems that help drivers make better decisions and reduce automobile accidents and fatalities.
Freescale silicon and software are accelerating the availability of ADAS for mainstream vehicles. Featuring scalability, low power consumption and high levels of integration, Freescale offers the industry's most complete selection of microcontrollers, sensors and analog devices for ADAS. Using Freescale technology, auto equipment manufacturers are able to simplify the highly complex development process and reduce time to market for front, rear and surround cameras, as well as radar for adaptive cruise control.
Adaptive cruise control is enabled by radar, which allows continuous monitoring of the vehicle's field of view. Freescale's transmitter solution supports radar sensing up to a 200-meter range and enables the determination of the distance and closing rate between the vehicle and other objects, including cars, stationary objects or pedestrians. If the radar system detects an impending collision, active braking could be applied to prevent an accident if the driver doesn't respond.
"Freescale is working to make active safety applications more cost-effective for mainstream vehicles, making the roads safer for everyone," said Dan Viza, director of Millimeter Wave Products at Freescale. "The Xtrinsic PRDTX11101 transmitter reduces the cost and complexity of 77 GHz automotive adaptive cruise control and long-range radar applications as well as short-range automotive applications, such as blind spot detection, lane change assist and cross traffic alerts."
The new radar transmitter is manufactured using 0.18 µm SiGe BiCMOS technology, which enables integration of the digital control functions in CMOS with millimeter wave frequency capabilities. The integrated VCO combined with power amplifier (PA) stages reduces system complexity and enables a smaller customer circuit board size. The transmitter also features low phase noise, coupled with low power consumption and a wide tuning range, improving the fidelity of the signal and enabling the device to be tuned to a range optimized for specific conditions or applications.
