SBC-C20 offer a dedicated embedded Display Port
CN21
interface.
For the connection of this kind of displays, on-board there
Signal
is a VESA
VCC_LCD_SW
interface, type STARCONN p/n 300E40-0110RA-G3 or equivalent (microcoaxial cable connector,
0.5mm pitch, 40 positions). This interface is multiplexed with the HDMI interface (par 3.3.6).
VCC_LCD_SW
On this connector, VCC_BKL_SW and VCC_LCD_SW are the software-enabled voltage rails that
VCC_LCD_SW
can be used to supply the LCD and related Backlight Unit.
GND
The LCD software-driven voltage, i.e. signal VCC_LCD_SW, can be manually configured to be
connected to VDD_3P3V or +5V_ALW. Please check par. 3.3.23 for details.
eDP_AUX_N
Instead, the backlight software-driven voltage, i.e. signal VCC_BKL_SW, can be factory regulated
eDP_AUX_P
regulated to be connected to +5V_ALW or VIN_SYS
GND
These are factory configurations, please take care of specifying which is the configuration needed
eDP_ML0P
for VCC_BKL_SW voltage rail.
eDP_ML0N
Here following the signals involved in eDP management:
GND eDP_ML0P/eDP_ML0N : embedded DP differential data pair #0.
eDP_ML1P/eDP_ML1N : embedded DP differential data pair #1.
eDP_ML1P
eDP_ML2P/eDP_ML2N : embedded DP differential data pair #2.
eDP_ML1N
eDP_ML3P/eDP_ML3N : embedded DP differential data pair #3.
GND
eDP_AUXN/eDP_AUXP: embedded DP auxiliary channel differential data pair.
eDP_ML2P
eDP_HPD: embedded DP Hot Plug Detect. +VDD_3P3V electrical level signal.
