Yes. > Sorry, I do not understand a second MAC, what does this mean? The MAC is the controller for an Ethernet port. Also, IIRC your MAC, the FEC, does not produce a "real" PPS output generated in Hardware. Instead, the driver does it, resulting in a very jittery PPS signal. (Maybe I'm mixing up the devices -- I don't have an imx myself -- but I would check this before building a product on it!)
