Component, headers, and MCU selection complete after confirming compatibility on data sheets. Figured out powering board / supplies needed as well as voltage step-down circuitry. Notes below.
Digital
3.3V VDDIO for high speed IO pins like MODCLK
Lots of switching noise, supply wires and layers must be carefully designed and isolated in a separate supply island on the PCB
-> step down to 1.8V for VDD VDDPLL
Analog
+5V for internal analog circuits
External Power Supply (for now)
+10V VDDPXH pixel field circuit
-10V VBS biasing pixel field
Progress is on schedule!
Next week: Layout PCB through Altium Designer
