Hello!
My team and I are working on a project that involves a portable, handheld device and a custom made docking station for that device. The portable itself will contain hardware that will generate a 2-lane DisplayPort video signal that we would like to output over USB-C to our docking station that will then convert the video to HDMI before going to a normal monitor/TV.
My question is whether or not the example "CCG2 Type-C to DisplayPort" reference design is a good design to follow. It seems as though that design is taking a USB-C input, handling the Alt Mode and Billboard handshaking, and then outputting a DisplayPort signal. We want the opposite - a solution acts as a DisplayPort source to be transmitted over USB-C. Does Cypress have a solution like this that exists?
Our portable also has a LiPo battery that needs to be charged from this USB-C cable such that the portable is a DisplayPort source but a power sink. There aren't any cases where our portable would act as a power source that would supply power across the USB-C cable. I was hoping to use TI's TPS25750 to handle this USB PD negotiation, but I don't think that will work well with this DisplayPort Alt Mode ecosystem. Will the Cypress CYPD2119-24LQXIT be able to handle these PD negotations on top of handling the DisplayPort Alt Mode?
Please let me know if this doesn't make sense and I can absolutely provide more information.
