This ASIC is part of safety and surveillance systems, ADAS (Advanced driver-assistance systems) and gesture recognition applications. It uses a laser-pulsed oF (Time-of-Flight) detection principle to calculate the distance to objects using a state-of-the-art 16-bit resolution TDC (Time-to-Digital Convertor). The design is tailored towards functional safety SIL-2.
