is there example connection diagram for CYUSB4347 gigabit ethernet DS5 port
thank you in advance.
There is no reference design with HX3PD with gigabit ethernet on a downstream port.
But you could refer to the CCG4 Dock reference design which has gigabit ethernet on DS4 of HX3, using GX3, our USB-to-ethernet controller.
Similar design can be implemented on HX3PD on DS5 as well with a USB-to-ethernet controller.
