Texas Instruments Inc. (TI) has rolled out a portfolio of automotive lidar, clock and radar chips for autonomous vehicles and advanced driving assistance systems (ADAS).
TI claims it has introduced the industry’s first integrated high-speed lidar laser driver, dubbed LMH13000, designed to improve real-time decision making in autonomous cars.
The company has also introduced what it claims is the industry’s first automotive BAW-based clocks, called the CDC6C-Q1 oscillator, and the LMK3H0102-Q1 and LMK3C0105-Q1 clock generators for ADAS reliability.
Lastly, the AWR2944P millimeter wave (mmWave) radar sensor for advanced front and corner radar capabilities.
30% longer
The integrated high-speed laser driver offers up to 30% longer distance measurements than discrete solutions, TI said. The lidar device also supports an average 30% reduction in systems costs while reducing board space by four times. This aims to reduce the cost of lidar modules by shrinking its size.
Other features of the lidar device include:
- Higher output currents
- Vast variations in pulse duration over temperature
- Up to 5 A of adjustable output current across -40° C to 125° C ambient temperature range
- Shore pulse-width generation
- Current control
Meanwhile, the ADAS electronic components increase reliability by 100 times compared to traditional quartz-based clocks with a failure-in-time rate of 0.3.
Other features of the ADAS chip include:
- Improved signal-to-noise ratio
- Increased computational capabilities
- Larger memory capacity
- Integrated radar hardware accelerator
