VGA and LVDS
A separate VGA and LVDS route to the COM Express connector from Ibex Peak-M. The VGA
support resolution is 1600 x 1200 or higher. The VGA signals are routed to the COM Express
connector directly.
The Intel Low Voltage Differential Signaling (LVDS) transmitter serializer converts up to 24 bits
of parallel digital RGB data (8 bits per pixel) and dual-channel, along with up to 4 bits for control
(SHFCLK, HSYNC, VSYNC, DE) into two channels (Channel A and Channel B). LVDS signals are
routed to COM Express connector directly.
To avoid SMbus address conflicts between SODIMM SPD and AT24C02, pin A2 of AT24C02
should be "1".
