The ADTF3175 is a complete Time-of-Flight (ToF) module for high
resolution 3D depth sensing and vision systems. Based on the
ADSD3100, a 1 megapixel CMOS indirect ToF (iToF) imager, the
ADTF3175 also integrates the lens and optical band-pass filter for
the imager, an infrared illumination source containing optics, laser
diode, laser diode driver and photodetector, a flash memory, and
power regulators to generate local supply voltages. The module is
fully calibrated at multiple range and resolution modes. To complete
the depth sensing system, the raw image data from the ADTF3175
is processed externally by the host system processor or depth
image signal processor (ISP).
The ADTF3175 image data output interfaces electrically to the host
system over a 4-lane mobile industry processor interface (MIPI),
Camera Serial Interface 2 (CSI-2) transmitter interface. The module
programming and operation are controlled through 4-wire serial
peripheral interface (SPI) and I2C interface.
APPLICATIONS
The ADTF3175 has module dimensions of 42 mm × 31 mm × 15.1
mm and is specified over an operating temperature range of −20°C
to 65°C.
