Using the Lontium LT1146A
Ah so the design ive been working on so has the Vbus lines and cc lines go to a different chip to the USB C and DP lines and i dont think the tusb1046 is asking about the usb source/sink role.... i think for my initial this wont be a problem as i want to make a carrier board for the cm5 that only has a single usb c port on it that you plug in to a usb c dock for power break out to a usb hub and Display. but for future boards this will be more of a problem as i would like this port to act more like a convential usb c port on a laptob able to be a usb c host and provide power ie for devices but also be a sink for power
