GENERAL DESCRIPTION

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.

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.
