>>4192155An Evertz master sync generator is one of the several sync generators that I have used. These are meant to be rack mounted, preferably in a server room or a flypack. These generators have a stable cooled oscillator inside that guarantees minimal drift over time when used standalone. They all have analog LTC outputs. The cameras you listed do support that. However, the cost of each such generator runs in the thousands, and as you can see they aren't meant to be carried – they need big teams of people to maintain and serve more purposes than just generating timecode.
