CXA Video Encoder (Neo Geo AES)

2min

The video encoding for generating composite and RGB video data from the LSPC chip is the CXA1145 video encoder.
The CXA1145 is a super common encoder found on many retro consoles.

RGB Amplification
The CXA1145 slightly amplifies the input RGB signals by around 40%. As an example, a blue in signal pulsing at 0.66V will output at 0.93V.
