CRT_IRTN

CRT_IRTN: this signal is the complement video signal output from 

the internal color palette DAC channels and this signal connects 

directly to the ground plane of the board

O

Analog

CRT_IREF

DAC_IREF Resistor:   resistor for the internal color palette DAC 

reference circuit. A 649 Ohm 0.5% resistor is required to be 

connected between DAC_IREF and the board ground plane. 

O

Analog

CRT_HSYNC

CRT Horizontal Synchronization: This signal is used as the vertical 

sync (polarity is programmable) or “sync interval”. 3.3V output. 

O

HVCMOS

CRT_VSYNC

CRT Vertical Synchronization: This signal is used as the vertical sync 

(polarity is programmable). 3.3V output.
