LVDS/eDP
The conga-MA5 offers a single channel LVDS interface on the COM Express connector. The interface is provided by routing the onboard
PTN3460 eDP to the eDP port of the SoC. The bridge processes the incoming DisplayPort stream, converts the DP protocol to LVDS protocol
and transmits the processed stream in LVDS format. The LVDS interface supports:
• single channel LVDS interface (color depths of 18 bpp or 24 bpp)
• integrated flat panel interface with clock frequency up to 112 MHz
• VESA standard or JEIDA data mapping
• automatic panel detection via Embedded Panel Interface based on VESA EDID™ 1.3
• resolution up to 1280x1024 @60Hz
The LVDS interface provides LVDS signals by default, but can optionally support eDP 1.3 signals at 3840x2160 @60Hz (assembly option). For
more information, contact congatec technical support.
Note
The LVDS/eDP interface supports either LVDS or eDP signals. Both signals are not supported simultaneously. See Table 11 for possible display
combinations.

SD Card
The conga-MA5 offers a 4-bit SD interface connected to the SD v3.01 host controller integrated in the SoC. It supports up to 50 MHz 3.3V
signalling. The MMC standard is not supported.
5.9
General Purpose Serial Interface (UART)
The conga-MA5 offers two UART ports routed from the SoC by default. Optionally, the UART ports can be routed from an LPC controller (Exar
XR28V382) instead. See
Note
The UART ports routed from the SoC cannot be used under Windows because Intel
®
does not provide the necessary driver. The UART ports
routed from the SoC can only be used under Linux.
The UART ports routed from the LPC controller (Exar XR28V382) can also be used under Windows 10 without a special driver.
