Hi Anston, thanks for your reply. Managing the voltage domains I'm not concerned about. However, I do need to find out about the duty cycle. The datasheet shows the sync pin being driven by a short pulse. What will happen if the sync pin is driven by a square wave?
Also, what would happen if the sync pin were to be held low for an extended period of time? Would the chip still operate, on its own clock? Or would it shut down?
