eDP Connector
As mentioned in paragraph 3.3.12, the CCOMe-C30 carrier board is also able to manage eDP
Displays, when jumper JP10 is in position.
For the connection of this kind of displays, on-board there is a VESA
®
certified connectors for
embedded Display Port interface, type STARCONN p/n 300E40-
0110RA-G3 or equivalent (microcoaxial cable connector, 0.5mm
pitch, 40 positions).
On this connector, VDD_BKLT and VDD_LVDS are the voltage rails that can be used to supply
the LCD and related Backlight Unit (please check par. 3.3.13)
Here following the signals involved in eDP management:
/eDP_TX0-: embedded DP differential data pair #0.
/eDP_TX1-: embedded DP differential data pair #1.
/eDP_TX2-: embedded DP differential data pair #2.
/eDP_TX3-: embedded DP differential data pair #3.
/eDP_AUX-: embedded DP auxiliary channel differential data pair.
eDP_HPD: embedded DP Hot Plug Detect. Active high signal.

PTN_PWR: 3.3V_S derived voltage for external eDP-to-LVDS bridge adapter. This power rail
will be enabled only in case jumper JP13 is placed, according to the table on the bottom of this
page
PTN_SMB_CLK: SM Bus control clock line for external eDP-to-LVDS bridge adapter. Output
signal, electrical level PTN_PWR.
PTN_SMB_DAT: SM Bus control data line for external eDP-to-LVDS bridge adapter. Bidirectional signal,
electrical level PTN_PWR.
