Flat Panel features:
• Supports (+3.3V or +5V, and +12V) output to LCD flat panels through an LVDS interface
• Supports panel sizes from VGA (640 x 480) up to UXGA+ (1600 x 1200).
• Supports 1-channel (18-bit) or 2-channel (36-bit) LVDS outputs
CRT Interface
Table 3-12 describes the pin signals of the CRT interface, which uses 10 pins, 2 rows, odd/even, (1, 2) with
0.100" (2.54mm) pitch.
Note: The shaded area denotes power or ground.
LVDS Interface
Table 3-13 describes the pin signals of the LVDS interface, which uses 30 pins, 2 rows, odd/even, (1, 2) with
.079" (2mm) pitch.
Table 3-12. CRT Interface Pin/Signal Descriptions (J3)
