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 ohm routing impedance but the terminating resistor to
ground will be 75 ohms. (e.g., 75 ohm resistor on the board, in
parallel with a 75 ohm CRT load).
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 ohm routing impedance but the terminating resistor to
ground will be 75 ohms. (e.g., 75 ohm resistor on the board, in
parallel with a 75 ohm CRT load).
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 ohm routing impedance but the terminating resistor to
ground will be 75 ohms. (e.g., 75 ohm resistor on the board, in
parallel with a 75 ohm CRT load).
Resistor Set: Set point resistor for the internal color palette
DAC. A 255 ohm 1% resistor is required between CRT_IREF and
motherboard ground.
CRT Horizontal Synchronization: This signal is used as the
horizontal sync (polarity is programmable) or “sync interval”.
2.5 V output.
CRT Vertical Synchronization: This signal is used as the
vertical sync (polarity is programmable). 2.5 V output.
