LVDS is a serial broadband transmission standard, becoming more and
more important in automotive technology to transfer video data.
Data is transmitted differential on two signal lines with very low
voltage and current, and frequencies more than 1GHz up to 3GHz.
Therefore, appropriate connectors and cables are strongly required for
failure-free transmission.
LVDS Serializer and LVDS connector are mounted on the pluggable
LVDS top-board
(to be able to adapt these components to different
displays very fast).
The used serializer and the deserializer at its counterpart are
decisive for proper operation of a LVDS interface. The LVDS
connection does only operate properly in the case that all members
use compatible components.
For this reason, please specify the pixel clock frequency of the
receiver with your order.
The following connector is used for the MAX9247, DS90C241,
DS90UR905Q and DS90UB925Q top-boards:

The DS90UR905Q top-board can be made compatible to the
DS90UR906Q, DS90UR124 and DS90C124 serializers by configuration.
For compatibility to the above mentioned serializers, their assignment
must comply with the DS90UR905Q data sheet.
The DS90UB925Q top-board can be made compatible to the
DS90UB926Q and DS90UR906Q serializers by configuration.
For compatibility to the above mentioned serializers, their assignment
must comply with the DS90UB925Q data sheet.
The MAX9209 and MAX9213 top-boards are operating with four LVDS
channels (3x RGB data, 1x clock).
Therefore they have the following 10-pole connector:
