Is there a way to use the PPS signal generated by the RTC

[norman_xu]

Hello NV，

Our products use multiple different sensors. Before GPS timing, the RTC module of Jetson Orin NX needs to generate PPS signals, which are output to the MCU from the specified GPIO pin (gpio12), and then the MCU divides the frequency to trigger signals to different sensors.

Question: Does Jetson Orin nx/nano support generating PPS signals through the RTC module?

Hi norman_xu,

Are you using the devkit or custom board for Orin Nano?
What’s the Jetpack version in use?

Could you share the block diagram of your connections including Orin Nano, GPS, RTC, MCU?
What’s the interfaces you use for them?

It may depends on the capability of your RTC module.
As my understanding, PPS signal is generated from GPS module and used as input for Orin Nano.
