First Camera Link HS products shown at Vision 2014
Teledyne Dalsa, Matrox Imaging, and Silicon Software have all released products compatible with the Camera Link HS high-speed standard at Vision 2014 in Stuttgart, Germany. While the standard was ratified in May 2012, these are the first products available that comply with the standard.
Camera Link HS, which caters for high bandwidth data transfer in high-speed vision applications like flat panel display inspection, originated from HS Link, a protocol developed by Teledyne Dalsa for its high-speed vision products. Teledyne Dalsa exhibited its Piranha XL 16k CMOS TDI camera and its Xtium-CLHS PX4 frame grabber at the trade fair, both compatible with CLHS.
The Piranha XL 16k monochrome camera delivers 125kHz line rate, operating at 2GB/s data throughput using a single CX4 cable, while the Xtium-CLHS PX4 frame grabber is a PCIe Gen 2 board with up to seven CLHS data lanes to capture aggregate data rates of 2.1GB/s.
Both products are ideal for integration into flat panel, electronics, and semiconductor inspection systems, among other machine vision applications. The Piranha XL multi-line camera and Xtium-CLHS frame grabber are designed to help reduce inspection and manufacturing costs and enable the reliable transfer of information at high speeds.
The release of CLHS products makes the standard more competitive with the slightly older CoaXPress standard, also suitable for high-bandwidth vision applications. CLHS offers scalable bandwidths from 300MB/s to 16,000MB/s and low latency, low jitter, real-time signals between a camera and a frame grabber. CoaXPress, released 18 months earlier in December 2010, has a downlink speed of 6.25Gb/s per cable, transferring data over coaxial cable.
Matrox Imaging released the Radient eV-CLHS frame grabber at Vision in Stuttgart, while Silicon Software was displaying its MicroEnable 5 PCIe x8/Gen 2-based image acquisition and processing board.
The Radient eV-CLHS supports the Camera Link HS (v1.0) M-Protocol through a CX4 copper connection. It provides a single C2 7M1 connection for data transfers up to 2.1GB/s at cable lengths up to 15 metres. The card is equipped with a PCIe 2.0 x8 host interface and up to 4GB SDRAM of on-board buffering. The frame grabber has been tested for full compatibility with Teledyne Dalsa CLHS cameras.
