Description
Set Resistor. This signal sets the current
level for the RED/GREEN/BLUE analog out-
puts. Typically, a 464 , 1% resistor is con-
nected between this ball and AV
Analog Red, Green and Blue
TFT Clock. Clock to external CRT DACs or
TFT.
TFT Data Enable. Can be used as blank sig-
nal to external CRT DACs.
TFT Power Control. Used to enable power
to the Flat Panel display, with power
sequence timing.
Digital RGB Data to TFT.
TFTD[5:0] - Connect to BLUE TFT inputs.
TFTD[11:6] - Connect to GREEN TFT inputs.
TFTD[17:12] - Connect to RED TFT inputs.
