The chip includes both sensor array and conditioning circuitry, consisting of a timing generator (TG), an analog-to-digital converter (ADC), a depth engine, and an illumination driver.

The SoC includes an 80 by 60 pixel sensor array and the built-in timing generator offers the flexibility to optimize for various depth-sensing performance metrics including power, motion robustness, signal-to-noise ratio (SNR), and ambient cancellation.

Similarly a depth engine is built-in to the chip and computes the depth data from the digitized sensor data. In addition to the phase data, the depth engine provides auxiliary information consisting of amplitude, ambient, and flags for each pixel and the full-array statistical information in the form of a histogram.

The chip comes in a 56-pin package with an integrated optical band-pass filter for light at 830nm to 867nm wavelength that measures 8.03mm by 5.32mm by 0.745mm.
