LVDS Connector
In addition to HDMI, SBC-C43 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.
On the same connectors, are also implemented signals
power voltages for LCD and backlight (LVDS_VCC_BKL_SW and LVDS_VCC_LCD_SW) and
control signals (Backlight enable signal, LVDS_BKL_EN, LCD enable signal, LVDS_VDD_EN, PWM
and Analog Backlight Brightness Control signal, LVDS_BKL_PWM and LVDS_BKL_ANA).
The LCD software-driven voltage, i.e. signal LVDS_VCC_LCD_SW, can be factory regulated to be
connected to +5V_ALW or +3.3V_ALW, while backlight software-driven voltage, i.e. signal
LVDS_VCC_BKL_SW, can be factory regulated to be connected to +5V_ALW or +12V_ALW
These are factory configurations, please take care of specifying which is the configuration needed
for LVDS_VCC_LCD_SW and LVDS_VCC_BKL_SW voltage rail.
When building a cable for connection of LVDS displays, please take care of twist as tight as possible
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.
