Part Number: TDC7200
Other Parts Discussed in Thread: TIDA-00663

Dear Authorized;

I want to use TDC7200 on infrared or laser time of flight sensor.

In datasheet, there is a recomended front end chip(TDC100) for ultrasonic sensor.

Is there any recomended front end chip for laser or infrared?

Is TDC7200 is proper for laser or infrared sensor?

Is there any TI design for laser or infrared sensor?

Best Regards.

Refer to the LIDAR Pulsed Time of Flight Reference Design (TIDA-00663) at http://www.ti.com/tool/TIDA-00663?jktype=design for an example implementation in using the TDC7200 in a laser sensor application. See the TDC7200 for additional FAQs on laser sensing applications: https://e2e.ti.com/support/sensors/f/1023/t/724028

Dear Akeem;

Thank you for your answer.

How can I increase resolution of TOF measurement?

Best Regards.

user5866401,

The frequency of your CLOCK pin input determines the resolution, accuracy, and standard deviation of your measurement. By increasing the CLOCK frequency, you will improve all three characteristics. See datasheet section 9.4 CLOCK Recommendations for more details on configuring the appropriate CLOCK reference for your application.
