X64-CL iPro Series User's Manual

Data Port Summary

The Camera Link interface has three configurations. A single Camera Link connection is limited to 28 bits requiring some cameras to have multiple connections or channels. The naming conventions for the three configurations are:

• Base:

Single Channel Link interface, single cable connector.

• Medium:

Two Channel Link interface, two cable connectors.

• Full:

Three Channel Link interface, two cable connectors.

A single Camera Link port is defined as having an 8-bit data word. The "Full" specification supports 8 ports labeled as A to H.

Camera Signal Summary

Video Data

Four enable signals are defined as:

• FVAL

Frame Valid (FVAL) is defined HIGH for valid lines.

• LVAL

• DVAL

• Spare

Line Valid (LVAL) is defined HIGH for valid pixels.

Data Valid (DVAL) is defined HIGH when data is valid.

A spare has been defined for future use.

All four enables must be provided by the camera on each Channel Link. All unused data bits must be tied to a known value by the camera.

Camera Controls

Four LVDS pairs are reserved for general-purpose camera control, defined as camera inputs and frame grabber outputs.

• Camera Control 1 (CC1)

• Camera Control 2 (CC2)

• Camera Control 3 (CC3)

• Camera Control 4 (CC4)

Note: the X64-CL iPro by default implements the control lines as follows
