LVDS Connectors
4.6.1 F&S JAE FI-S25P connector on top side
The single channel LVDS display port on top side can be direct connected to a LVDS 18 or
24 bit display.
The VLCD voltage is 3.3V and switched on the baseboard. The current limit is 1.2 A.
Connector is a JAE FI-S25P-HFE. Matching connector on display cable is a crimp connector
FI-S25S housing and a cable with FI-C3-A1-15000 crimp contacts.
This connector is used because a wide range of displays does have a JAE FI-S series
connector (with different pinouts) and it's easy to handle identical crimp contacts for the cable
manufacturer.

Pin 1 is marked on the connector with an arrow and also marked on PCB.
The single channel LVDS port can be direct connected to a LVDS 18 bit display.
Unused signals should be left unconnected.
