Does the OAK-SoM have a time synchronization protocol to synchronize time to the host processor, for example the PPS (pulse per second) seen in GPS devices? I am looking into using the OAK-SoM (with stereo cameras) connected to a Linux host system that will host other type of sensors. The host system will be timestamping data from the other sensor and acquiring the timestamped OAK-SoM data. There is a need to correlate the time of the two datasets from the host and OAK-SoM systems.
From the OAK-SoM datasheet, I see it outputs the 24 MHz camera clock reference. This is a start as it can drive a clock on the host system side, but I don't see any other signals to help correlate to system clocks.
