Is anybody able to give feedback on the following schematic please?
I'm trying to design an open source CM3 prototyping board that has hand soldering friendly components, so I'm hoping to replace the BGA ESD5384 with a TSSOP TPD12S016:
I have pulled LS_OE and CT_HPD high via 10K resistors, I believe this should disable any power saving and ensure the i2c lines are pulled up appropriately.
As far as I can tell, HDMI_HPD is active low, so I have used a mosfet inverter for this (in line with the original schematic). I figure it made more sense to put this in between the CM3 and the ESD IC.
My main concern is the CEC line, I'm not sure what to do with it and I'm not sure what the function of Q3 is in the original schematic:
According to the datasheet, CEC is pulled up internally.
Datasheet for the aforementioned ESD IC:
