Customer manufacturing calibration flow

Figure 6 shows the recommended calibration flow that should be applied at customer level,

at factory, once only. This flow takes into account all parameters (cover glass, temperature &

voltage) from the application.

2.3.1

SPAD and temperature calibration

In order to optimize the dynamic of the system, the reference SPADs have to be calibrated.

Reference SPAD calibration needs to be done only once during the initial manufacturing

calibration, the calibration data should then be stored on the Host.

Temperature calibration is the calibration of two parameters (VHV and phase cal) which are

temperature dependent. These two parameters are used to set the device sensitivity.

Calibration should be performed during initial manufacturing calibration, it must be

performed again when temperature varies more than 8degC compared to the initial
