(1)

To achieve the full distance, the oscillator need to be tuned to 4.7 MHz. Use ams OSRAM reference code to implement

clock frequency tuning.

Any target reported above 2500 mm should be considered as no object.

360 lux halogen light represents 2.5 k sunlight equivalent; light on object only.

(3)

1400 lux halogen light represents 10 k sunlight equivalent; light on object only

(4)

14000 lux halogen light represents 100 k sunlight equivalent; light on object only

VCSEL

Internal protection ensures no single point of failure will cause the VCSEL to violate the Class 1 Laser

Safety.

Laser Safety

Class 1

●

VCSEL Pulse Rep Rate

23 ns (43 MHz; 37.6 MHz if clock frequency tuned to 4.7MHz)

If VCSEL_clk_div=1 the frequency is divided by two.

TOF Sensor Field of View (FOV) 37º

FWHM

– for short distances

24º

FWHM

– for long distances

The SPAD FoV angular response uses the full TMF8801 SPADs for short distances. The SPAD FoV

is reduced when the TMF8801 operates in long distance since the SPAD array is reduced. This helps

to improve ambient light tolerance.
