LVDS + backlight connector
SBC-C20 board can be interfaced to LCD displays using its LVDS
interface, which allows the connection of displays with a colour depth of
18 or 24 bit, single or dual channel.
For the connection, a connector type HR A1014WV-S-2X25P or
equivalent (2 x 25p, male, straight, P1, low profile, polarized) is provided,
with the pin-out shown in the table below.
Mating connector: HR A1014H -2X25P with HR A1014-T female crimp
terminals.
Alternative mating connector, MOLEX 501189-5010 with crimp terminals series 501334.
power voltages for LCD and backlight (VCC_BKL_SW and VCC_LCD_SW) and control signals
(Backlight enable signal, DISPLAY_BKL_ON, LCD enable signal, LVDS_PANEL_ON, PWM and
Analog Backlight Brightness Control signal, DISPLAY_BKL_CTRL and DISPLAY_ANA_BKL).
When building a cable for connection of LVDS displays, please take care of twist as tight as possible
terferences. Shielded cables are also
recommended. Here following the signals related to LVDS management:
LV/LVDS0_TX0-: LVDS Channel #0 differential data pair #0.
LV/LVDS0_TX1-: LVDS Channel #0 differential data pair #1.
LV/LVDS0_TX2-: LVDS Channel #0 differential data pair #2.
LV/LVDS0_TX3-: LVDS Channel #0 differential data pair #3.
LV/LVDS0_CLK-: LVDS Channel #0 differential Clock.
LV/LVDS1_TX0-: LVDS Channel #1 differential data pair #0.
LV/LVDS1_TX1-: LVDS Channel #1 differential data pair #1.
LV/LVDS1_TX2-: LVDS Channel #1 differential data pair #2.
LV/LVDS1_TX3-: LVDS Channel #1 differential data pair #3.
LV/LVDS1_CLK-: LVDS Channel #1 differential Clock.
12V_BKL1, 12V_BKLT2: 12V power rails, directly connected to Input Voltage VIN_SYS, fuse
protected (max 1.85A per rail).
VCC_BKL_SW: SW enabled Backlight power rail. Please check par. 3.3.23
