Description
CRT Vertical Synchronization: This signal is used as the vertical sync signal.
CRT Horizontal Synchronization: This signal is used as the horizontal sync signal.
Red (Analog Video Output): This signal is a CRT Analog video output from the internal
color palette DAC. The DAC is designed for a 37.5 Ω equivalent load on each pin (e.g.,
75 Ω resistor on the board, in parallel with the 75 Ω CRT load).
Red# (Analog Output): Tied to ground.
Green (Analog Video Output): This signal is a CRT analog video output from the internal
color palette DAC. The DAC is designed for a 37.5 Ω equivalent load on each pin (e.g.,
75 Ω resistor on the board, in parallel with the 75 Ω CRT load).
Green# (Analog Output): Tied to ground.
Blue (Analog Video Output): This signal is a CRT Analog video output from the internal
color palette DAC. The DAC is designed for a 37.5 Ω equivalent load on each pin (e.g.,
75 Ω resistor on the board, in parallel with the 75 Ω CRT load).
Blue# (Analog Output): Tied to ground.
