The differential LVDS signals X0-X3 and XCLK are reserved for the transmission
of high-speed video data from the camera to the grabber board. The video data
is transmitted using numerous serial channels simultaneously, according to the
protocol for the channel link chipset from National Semiconductor.
The CameraLink standard defines the names of the pixel signals, the description of
the signal level and the pin assignments and pinout of the chip.

Warning: FVAL and DVAL are not used here as defined in the CameraLink standard.
FVAL is always set to the value = 1 (low).
DVAL is always set to the value = 1 (high).
