VL53L9CX – Optical Filter and Power Supply Noise Requirements

[Elbin]

Could you please share the detailed optical filter characteristics of the filter integrated in front of the VL53L9CX receiving sensor, including its spectral transmission/response characteristics?

Also, I would like to understand the power supply noise sensitivity of the sensor. Could you please provide the acceptable input voltage deviation, ripple, and noise limits for the sensor's power supplies?

Hi Team,

Gentle reminder on the request. Could you please help us with your recommendation?

Thanks,

Elbin

Hello ​@Elbin,

The optical filter characteristics can be found in the datasheet DS14879, in the 2.4 Bandpass filter section - table 5.

For the power supply noise, you can find all the information in the 2.10 Power management section - table 8. It specifies the acceptable tolerances for the power rails. Please make sure that the voltage always remains within these limits.

Let us know if it answers your questions.

Thanks, Megane
