Time-of-flight sensor XTOF-100-A

Product overview
The XTOF-100-A is a monolithic, fully integrated CMOS Time-of-Flight (ToF) system-on-chip designed for optical distance measurement and object detection in industrial sensing applications.

Detailed description
The XTOF-100-A integrates an 8 × 8 cwToF pixel imager, precision A/D converter, on-chip controller and an integrated high-current LED or laser-diode driver to provide a complete acquisition and processing chain on a single die. Operating modes include high-speed single-pixel ranging and full 8 × 8 ToF imaging to support both point measurement and low-resolution depth mapping.
