COMe-cCT6 / Features and Interfaces

Digital Display Interface Features

The integrated Intel® GMA 3650 / 3600 graphics supports:

» High-bandwidth Digital Content Protection (HDCP)

» One active Protected Audio and Video Path (PAVP) session

» DP and HDMI Hot-plug (low-active)

DDI Design Consideration

» For sufficient signal quality baseboard designs with long signal lanes or impedance leaps may require an Equalicer

or Redriver for the digital display interfaces

» Monitor Hot-plug detection is usually high-active. On COMe-cCT6 the hot-plug is low active and requires conversion

on the baseboard

» SDVO can be used for external conversion to VGA, LVDS, TV-out and requires additional hardware on your baseboard

» DisplayPort can be used directly or with external adapters for HDMI, DVI or VGA

» HDMI or DVI usage on a baseboard requires a level shifter
