TIDA-00663: Question about hardware degn of LIDAR Pulsed Time of Flight Reference Design(TIDA-00663)

Part Number: TIDA-00663

Hello

Here is a part of the TIDA-00663,LIDAR Pulsed Time of Flight Reference Design.I don't know what is frequence and pulse width of signal BP11_CAL(GPIO), and is it a square wave signal?

and when the sinal GATE_DRV and BP11_CAL(GPIO) is set to high, what is voltage of the signal laser_on ?

Could any experts please explain it to me?

Hi,

BP11_CAL is a unit step signal that goes from 0 to 3.3V once a calibration function is performed.

In order to understand what happens when BP11_CAL is set to high I suggest you to look at the attached simulation file.

Thanks

Giovanni
