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.
