Effective zone orientation

The VL53L7CX module includes a lens over the RX aperture which flips (horizontally and vertically) the captured

image of the target. As a consequence, the zone identified as zone 0 in the bottom left of the SPAD array is

illuminated by a target located at the top right hand side of the scene.

Measurement conditions

The following criteria and test conditions apply to all the characterisation results detailed in this section unless

specified otherwise:

•

The specified target fills 100% of the field of view of the device (in all zones).

•

Targets used are Munsell N4.75 (17%) and Munsell N9.5 (88%).

•

AVDD is 2.8 V, IOVDD is 1.8 V.

•

Nominal ambient temperature is 23°C.

•

Maximum range capability is based on a 90% detection rate (1).

•

Range accuracy figures are based on 2.7 sigma ie 99.3% of measurements are within the specified

accuracy.

•

940 nm is equivalent to 5 kLux daylight.

•

All tests are performed without cover glass with a crosstalk margin set to 0 kcps.

•

The sensor relies on default calibration data.

•

The device is controlled through the API using the default driver settings.

1. Detection rate is a statistical value indicating the worst case percentage of measurements that return a valid ranging. For

example, taking 1000 measurements with 90% detection rate gives 900 valid distances. The 100 other distances may be

outside the specification or flagged with an invalid target status.
