HDMI to CSI Converter for raspberry pi
The wiring is not complete in any way and even now connecting a HDMI source will fry the chip as 5V line is connected to 2.5V supply. Multiple supply and ground pins are unconnected. Not only passives such as bypass capacitors and reference voltage set resistor are needed, but a lot of other active components as well, such as reference clock source like a crystal oscillator module and voltage regulators to generate all the required power supplies. I hope this answers the question.
