OPT8241
SBAS704A – JUNE 2015 – REVISED JUNE 2015
7.1 Overview
The OPT8241 is a high-performance quarter video graphics array (QVGA) resolution, 3D sensor device that
senses depth information based on the time of flight (ToF) technique. The OPT8241 has a CMOS image sensor
core with an integrated analog-to-digital converter (ADC), an addressing engine for the sensor core, an low-
voltage differential signaling (LVDS) serializer, and an I²C slave. The device supports configurable timings to
optimize power and performance.
The OPT8241 includes the following blocks:
• Timing generator (TG)
• Sensor core
• Addressing engine
• ADC and overload detection
• Modulation block
• Output block
• Temperature sensor
• I²C control interface
