Teledyne DALSA Xcelera-HS PX8

PCI Express x8 Frame Grabbers for HS-Link Interface

Building on the field proven technology and performance of Teledyne DALSA’s Xcelera-CL frame grabbers, the Teledyne DALSA Xcelera-HS Series leverages the PCI Express (PCIe) platform to bring traditional image acquisition and processing technology to new levels of performance and flexibility.

Advanced PCIe x8 image acquisition

The PCIe host interface is a point-to-point host interface allowing simultaneous image acquisition and transfer involving little intervention from the host CPU. Designed with the requirements of the machine vision OEMs in mind, the Teledyne DALSA Xcelera-HS PX8 combines HS-Link interface with onboard preprocessing functions such as shading correction, Bayer decoding etc.

Addressing the emerging needs of bandwidth-hungry machine vision applications, Teledyne DALSA’s Xcelera HS Series is defining next generation frame grabber capabilities to deliver image acquisition bandwidth of 1.8GB/s and host transfer bandwidth of 2GB/s over multiple-lane PCI Express implementations with room to grow.

The Teledyne DALSA Xcelera-HS PX8 has been built within Teledyne DALSA’s Trigger-to-Image Reliability technology framework. Trigger-to-Image Reliability leverages Teledyne DALSA’s hardware and software innovations to control, monitor and correct the image acquisition process from the time that an external trigger event occurs to the moment the data is sent to the host, providing traceability when errors do occur and permitting recovery from those errors.

Software Support

All of the frame grabbers in the Xcelera series are supported by Teledyne DALSA’s Sapera Essential software package. Sapera Essential, is a cost- effective machine vision software toolkit that bundles board level acquisition and control with advanced image processing capability, featuring a value added, all new geometric search tool.

Sapera Essential is designed to deliver the critical functionality needed to design, develop and deploy high-performance machine vision applications while at the same time significantly lowering deployment costs.

HS-Link interface

The HS-Link interface is a new machine vision connectivity interface pioneered by Teledyne DALSA. HSLink is designed specifically to meet the needs of all machine vision applications and therefore carries image data, configuration data and low jitter, real time triggering signals over a simple network topology supporting cameras, intermediate devices and frame grabbers. The interface has taken the key strengths of Camera Link, and added new features and functions. HSLink delivers scalable bandwidth of 300 to 6000 MB/s, 1x to 20x configurations while using globally available, off-the-shelf components.
