Classic high speed

The low voltage differential signals, LVDS, transmitted through the Camera Link cables have a low EMC susceptibility. However, a special frame grabber is required in the PC host. Using the Dual Camera Link standard (CL Medium and Full), data rates up to 850 MB/sec are achievable.

General knowledge of the Camera Link standard

The chronicle

Official logos for Camera Link and the Power-over-Camera Link (PoCL) standard.

The CL standard was first introduced in October 2000 by AIA, the Automated Imaging Association. With Camera Link rev. 1.1, the generic programming interface, GenICam, was added, allowing compliant devices and hardware to be controlled by conforming software. All SVS-Vistek cameras are GenICam compliant.

With the release of Camera Link Rev. 1.2 in 2007, additional features were incorporated by AIA. Noticeably Power-over-Camera Link, PoCL. With this addition and ever increasing data rates (from Base, via Medium up to Full and Deca configuration), higher performance is required from the grabber. EURESYS, SVS-Vistek’s innovative partner, is providing excellent support for all of our high end Camera Link cameras covering all of their features.

While the chip set used for Camera Link requires very little space, SVS-Vistek cameras with Camera Link have lower power dissipation than cameras equipped with other interfaces, e.g. GigE Vision. This is why Camera Link cameras are so well suited for space-constrained applications. Image processing is done remotely from the image acquisition.

In addition to streaming raw data from the sensor, SVS-Vistek also offers Camera Link cameras capable of performing simple image correction pre-processing (e.g. hot pixels) in the camera.

CL interfaces and cables

The standard cable contains 26 individual leads. They are organized as twisted pairs, transmitting pixel data, sync and camera control (CC) signals as well as bi-directional serial communication.

PoCL requires minimum 2 extra lines.

The Camera Link standard specifies that the cable pairs be shielded. An addition, AIA also stipulates a secondary EMI shielding of the complete cable.
