Wiring harnesses, sometimes called cable assemblies or cable looms, are used in every corner of the electronics industry, including consumer appliances, commercial devices, robotics and industrial systems, computers and servers, telecommunications equipment, medical systems, aerospace platforms, and of course, trucks and automobiles. However, the wiring harnesses used in electric vehicles (EVs) are among the most […]
How do modular wiring harnesses support zonal architectures?
Vehicle wiring harnesses without a zonal architecture can have over 1,000 wires connecting over a hundred ECUs. They are difficult to fabricate and install, and changes can be difficult and costly to implement. However, using modular wiring harnesses in zonal architectures can overcome those challenges. A zonal architecture places electronic control units (ECUs) in multiple […]
What’s the difference between mini delta ribbon and shrunk delta ribbon cable assemblies?
Mini delta ribbon (MDR) and shrunk delta ribbon (SDR) cable assemblies are both designed to carry video signals as specified in the Camera Link (CL) specification, and they have the same internal connections. MDR and SDR cables are incompatible with the higher speed Camera Link HS (CLHS) standard. CLHS connectors include CX4 and SFP/SFP+. A […]
What are the seven variations of Camera Link Machine Vision connectivity?
Camera Link (CL) standardizes the hardware connection between cameras and frame grabbers. It includes specifications for data transfer, camera timing, serial communication, and real-time signaling. Camera Link variants include base, medium, full, deca, high speed (CLHS), PoCL (power over Camera Link), and PoCL Lite. Camera Link is a serial communication protocol standard maintained and administered […]
What are the most common connector styles used for MV systems?
Machine vision (MV) is an important tool in Industry 4.0, autonomous driving, and other advanced technologies. Various standard data connectors and application-specific vision system connectors support it. MV hardware consists of a camera or other imaging sensor and a computer that analyzes the images. Reliable, high-speed connectivity is required to link them. Examples of standard […]
How do car camera bus and FPD Link compare?
Car camera bus (C2B) and flat panel display (FPD) Link are both technologies used in automotive vision systems, but they differ in their use cases, performance, and cost. Automotive high-definition link (AHL) is another choice for video connectivity, as is automotive Ethernet, a general-purpose networking technology. This article briefly compares FPD Link, C2B, and AHL. […]
How twin axial cable assemblies support high-performance computing for AI/ML systems
The high-performance computing platforms used for artificial intelligence (AI) and machine learning (ML) in hyperscale data centers need high-speed interconnects like 112 Gbps PAM 4 and faster inside the servers. High-speed interconnects are also required between the servers and storage devices. Twin axial (Twinax) cable assemblies are one way to address those needs. This article […]
What specifications are needed for card edge connectors in AI/ML systems?
Card edge connectors connect peripheral devices or expansion cards to a host system. They provide a reliable interface for data transfer and power delivery, facilitating the integration of artificial intelligence (AI) components into a system. They support AI and machine learning (ML) on the edge, in the cloud, and in hyperscale data centers. This article […]
How do 224 G connectors support AI/ML training in hyperscale data centers?
224 Gigabits per second (Gbps) pulse-amplitude modulation 4-level (PAM 4) technology is foundational for the hyperscale data centers needed for artificial intelligence (AI) and machine learning (ML) training and implementation. This article begins by examining the multiple uses of 224 G connectivity in servers and storage devices. It then considers how multiple 224 G lanes […]
What interconnects are used with memory for HPC and AI?
High-performance computing (HPC) for artificial intelligence (AI) applications places extreme demands on memory connectors. They must deliver high-speed connectivity, high levels of signal integrity (SI), and support high-density solutions. This article reviews connector needs for Peripheral Component Interconnect Express 6.0 (PCIe 6.0), Serial Attached SCSI (SAS) including SAS 3.0, 4.0 and SAS/PCIe 5.0, and Data […]
