VL53L1X Ranging performances

3.5 Performances in ambient light conditions

3.5.1 Long distance mode

Test conditions (including those described in Section 3.1: Test conditions) are:

• Ambient light = dark, 50 kcps/SPAD, 200 kcps/SPAD

• Distance mode = long

3.5.2 Short distance mode

Test conditions (including those described in Section 3.1: Test conditions) are:

• Ambient light = dark, 200 kcps/SPAD

• Distance mode = short
