10/100 Base Ethernet
Ethernet controller (LAN9118) is mounted on this board so it is possible to communicate
10/100Base Ethernet with PC via RJ-45 connector.

LVDS I/O Connector
For high speed data access, two channels (Tx/ Rx) of LVDS connectors are mounted on this board.
There are 20 pair of data lines and 2 pair of clock line for each channel.
Although signal level is variable to select 2.5V or 3.3V, it is possible to select another I/O standard
not only LVDS.

High Speed Extension I/O Connector
For realizing variable interface, there are four connectors for option board shown by Figure.22.
It is possible to change the signal level to 2.5 or 3.3V according to connected interface.
Assuming the high speed image data input from an external device, the board provides 5 LVDS pairs
for data, 2 LVDS pairs for clock at differential 100 ohm impedance and other signal lines at single 50
ohm impedance. It also provides GND, VCC(2.5V,3.3V( and +12V power supply.
Note: For differential pair, refer in the following table.
