I want to be able to capture and process an analog video signal (composite, PAL), however my knowledge of analog is very well limited.
I am planning on using a 25MSPS ADC (Texas Instruments ads801 or similar) attached to a Cyclone V FPGA so no real issue regarding how much data I can take, but I have little clue of how to connect the analog signal to the ADC beyond "mind the voltage range"
Any common caveats or design rules or reference material I should read?
