Other Parts Discussed in Thread: TUSB546A-DCI, TPS25750
I am designing a carrier board for the Raspberry Pi CM4, which will have a USB C connector. It is planned for it to be a DFP data-wise, but a DRP power-wise, which accepts 5-20V 3A in but only 5V 3A out. It will also have HDMI out alternate mode using one of the CM4's HDMI outputs.
When connecting a TPS65987D to a TUSB546A-DCI through I2C, where do the HDMI I2C connections go? I assume they would be connected to I2C2, as the HDMI source acts as a master? In addition, which I2C port would be used to connect the TPS65987D to the TUSB546A-DCI? I assume I2C3, as the TPS65987D acts as a master?
Thanks in advance!
