Product overview
Description
The VD55H1 is a low-noise, low-power, 672 x 804 pixel (0.54 Mpix), indirect Time-of-Flight (iToF) sensor die manufactured on advanced backside-illuminated, stacked wafer technology. Combined with a 940 nm illumination system, it enables building a small form-factor 3D camera producing a high-definition depth map with typical ranging distance up to 5 meters in full resolution, and beyond 5 meters with patterned illumination. With a unique ability to operate at 200 MHz modulation frequency and more than 85% demodulation contrast, the sensor can produce depth precision twice as good as typical 100 MHz modulated sensors, while multifrequency operation provides long distance ranging. The low-power 4.6 µm pixel enables state-of-the-art power consumption, with average sensor power down to 80 mW in some modes.
The VD55H1 outputs 12-bit RAW digital video data over a MIPI CSI-2 quad lane or dual lane interface clocked at 1.5 GHz. The sensor frame rate can reach 60 fps in full resolution and 120 fps in analog binning 2x2. ST has developed a proprietary software image signal processor (ISP) to convert RAW data into depth map, amplitude map, confidence map and offset map. Android formats like DEPTH16 and depth point cloud are also supported.
The device is fully configurable through the I2C serial interface. It features a 200 MHz low-voltage differential signaling (LVDS) and a 10 MHz, 3-wire SPI interface to control the laser driver with high flexibility. The sensor is optimized for low EMI/EMC, multidevice immunity, and easy calibration procedure.
The sensor die size is 4.5 x 4.9 mm and the product is delivered in the form of reconstructed wafers.
