Description
Serial Port Clock Input
This pin functions as the clock pin of the serial port interface, and
uses the DVDDV supply.
DVI Swing Control
This pin sets the swing level of the DVI outputs. A 2.4K ohm resistor
should be connected between this pin and TGND using short and wide
traces.
DVI Data Channel 0 Outputs
These pins provide the DVI differential outputs for data channel 0
(blue).
DVI Data Channel 1 Outputs
These pins provide the DVI differential outputs for data channel 1
(green).
DVI Data Channel 2 Outputs
These pins provide the DVI differential outputs for data channel 2
(red).
DVI Clock Outputs
These pins provide the differential clock output for the DVI interface
corresponding to data on the TDC[0:2] outputs.
Current Set Resistor Input
This pin sets the DAC current.
connected between this pin and GND (DAC ground) using short and
wide traces.
TEST Input
This pin is used for factory test and should be tied to GND or left N/C.
Green Output
This pin will output the Green component of RGB when RGB
bypass mode is used.
Red Output
This pin will output the Red component of RGB when RGB
bypass mode is used.
Blue Output
This pin will output the Blue component of RGB when RGB
bypass mode is used.
No Connect
Vertical Sync Output
A buffered version of VGA vertical sync can be acquired from this pin.
