Description

CRT_RED

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).

CRT_REDB

RED# Analog Output: This signal is an analog video output

from the internal color palette DAC. It should be shorted to

the ground plane.

CRT_GREEN

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).

CRT_GREENB

GREEN# Analog Output: This signal is an analog video

output from the internal color palette DAC. It should be

shorted to the ground plane.

CRT_BLUE

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).

CRT_BLUEB

BLUE# Analog Output: This signal is an analog video

output from the internal color palette DAC. It should be

shorted to the ground plane.

CRT_IREF

I/O

Resistor Set: Set point resistor for the internal color palette

DAC.

CRT_HSYNC

HVCMOS

CRT Horizontal Synchronization: This signal is used as

the horizontal sync (polarity is programmable) or “sync

interval”, 3.3 V output

CRT_VSYNC

HVCMOS

CRT Vertical Synchronization: This signal is used as the

vertical sync (polarity is programmable) 3.3 V output.

CRT_DDC_CLK

I/O

COD

Monitor Control Clock: This signal may be used as the

DDC_CLK for a secondary multiplexed digital display

connector.

CRT_DDC_DATA

I/O

COD

Monitor Control Data: This signal may be used as the

DDC_Data for a secondary multiplexed digital display

connector.
