Time-of-flight sensor XTOF-102-A

Product Overview
The XTOF-102-A is a monolithic, fully integrated continuous-wave (cw) Time-of-Flight (ToF) system-on-chip (SoC) designed for optical distance measurement and object detection in industrial and embedded imaging applications.

Key Functionality
The XTOF-102-A integrates a QVGA (320 × 240) ToF imager, a programmable illumination driver (LED or laser), A/D conversion and an on-chip controller. It provides per-pixel 12-bit DCS distance data accessible via a high-speed 12-bit parallel video interface for direct acquisition and downstream processing.
