I'm currently using a CRT TV in my MAME arcade cabinet and I want to connect some arcade PCBs. (i.e. Neo Geo MVS)
The TV accepts component video (YPbPr) and I'm using an RGBHV (VGA) to Component transcoder (Crescendo TC1600). This is connected to a MAME PC using CRT Emudriver to output 15 kHz signals over DB15/VGA which is then converted to component.
Assuming I'm going to use a JAMMA breakout cable and have each of the signal wires (RGBs), how can I safely reduce the arcade RGB high amplitude (2-5v p-p) to a safe level (0.7v p-p) for my VGA transcoder?
I'm decent at soldering but can't wrap my head around understanding electronics. I think I need to reduce voltage and buffer (THS7374 amp?) the video but I'm not sure how to design the circuit (and what/how 75 Ohm termination is required, etc).
Thanks for any help!
