Table 3-10 defines the signals of the VGA interface, which consists of 10 pins, 2 rows, odd/even, (1, 2) with

0.079" (2mm) pitch.

Note: The shaded table cells denote power or ground.

Table 3-11 lists the pin signals of the LVDS video header, which provides 20 pins, 2 rows, odd/even pin

sequence (1, 2) with 0.079" (2mm) pitch.

Table 3-10. VGA Interface Pin Signal Descriptions (J17)

Pin # Signal Description

1 VSYNC Vertical Sync – This signal is used for the digital vertical sync (polarity is

programmable) 2.5V output to the VGA display.

2 HSYNC Horizontal Sync – This signal is used for the digital horizontal sync

(polarity is programmable) or “sync interval” 2.5V output to the VGA

display

3 DDC-CLK Display Control Clock

4 RED Red – This is the Red analog output signal to the VGA display.

5 DDC-DATA Display Control Data
