Xtium-CL MX4 User's Manual Camera Link Interface • 117
Camera Signal Summary
Video Data
Four enable signals are defined as:
• FVAL Frame Valid (FVAL) is defined HIGH for valid lines
• LVAL Line Valid (LVAL) is defined HIGH for valid pixels
• DVAL Data Valid (DVAL) is defined HIGH when data is valid
• Spare A spare has been defined for future use
The camera provides the four enables on each Channel Link. All unused data bits must be set 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 Xtium-CL MX4 by default implements the control lines as follows,
(using Teledyne DALSA terminology):
• (CC1) EXYNC
• (CC2) PRIN
• (CC3) FORWARD
Communication
Two LVDS pairs are allocated for asynchronous serial communication to and from the camera and
frame grabber. Cameras and frame grabbers should support at least 9600 baud.
• SerTFG Differential pair with serial communications to the frame grabber
• SerTC Differential pair with serial communications to the camera
The serial interface protocol is one start bit, one stop bit, no parity, and no handshaking.
