All Hot Plug Detect Input signals (valid both for DP++ and TMDS interface) are +3.3V_RUN electrical level signal, active high with 100KΩ pull-down resistors.

All HDMI Control /DP AUX signals (DDIx_CTRLCK_AUX+ and DDIx_CTRLDATA_AUX-) are bidirectional signal, electrical level +3.3V_RUN with a 100kΩ pull-up (on

Data) / pull-down (on clock) resistor

Please be aware that for correct implementation of HDMI/DVI interfaces, it is necessary to implement, on the Carrier board, voltage level shifter for TMDS differential

pairs, for Control data/Clock signals and for Hot Plug Detect signal.

Voltage clamping diodes are also highly recommended on all signal lines for ESD suppression.

Please remember that modules configured with the VGA video output will use the DDI Port #2 to drive the DP-to-VGA bridge. This means that on

these modules, the DDI interface #2 will not be externally available.

Please take care of specifying if VGA interface is needed, before placing an order of COMe-C55-CT6 module.
