2-4 Camera Link & USB3-FRM13
USB3-FRM13 supports Camera Link Base/Medium/Full Configuration. Base Configuration, 24
data bits and four enable signals Frame Valid, Line Valid, Data Valid and a spare, including 28-bit
parallel signals serialized four LVDS signal lines and one LVDS signal line to fit the camera and
synchronous LVDS signal lines including four CC (Camera Control) signal and full 11 includes two
asynchronous serial communication to communicate with the camera LVDS lines, is transmitted
through one MDR cable. In order to use the MDR Medium / Full Configuration is used other cable
and has a total 64bit wide video path.
The transmitted signal parallelizes 12 video LVDS serial signals into 64-bit parallel video signals
and control signals for each specification (Frame Valid, Line Valid, Data Valid, and a spare) through
the Channel Link chip in USB3-FRM13. In addition, one LVDS to synchronize the signal between
the camera and the USB3-FRM13 makes a clock signal, and the remaining cameras control signals
and communication signals are converted into general TTL signal levels and used.

Camera Control
Above picture is a Camera Control output circuit from USB3-FRM13 board to Camera for the
specific control of the Camera-link Cable. The USB3-FRM13 board has four differential digital
outputs. Each output is mapped by Digital output. Below picture [Figure 2-7] display that each bit
position set.
