3 Description

The time-of-flight controller (TFC) is a high-performance, 3D time-of-flight (ToF) sensor companion device that computes the depth data from the digitized sensor data. Depth data are output via a programmable complementary metal-oxide-semiconductor (CMOS) parallel interface.

In addition to depth data, the TFC provides auxiliary information consisting of amplitude, ambient, and flags for each pixel. This information can be used to implement filters and masks and to dynamically control the system configuration for the intended performance.

The TFC supports a wide range of binning and ROI options that help optimize the data throughput that must be handled.

The 9-mm × 9-mm NFBGA package enables small form-factor, 3D, ToF systems that can be embedded into a variety of end equipment.
