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
6 GREEN Green – This is the Green analog output signal to the VGA display.
7 VDD5V0 Power – This is the +5 volts +/- 5% power signal from the external power
interface.
8 BLUE Blue – This is the Blue analog output signal to the VGA display.
9 GND Ground
10 GND Ground
