Maxim Integrated's Serial-Data Chipsets Transmit over Coax Cables, Lower Automotive Camera System Cable and Connectivity Costs by 50%

Maxim Integrated Products, Inc. (NASDAQ: MXIM) introduces two high-speed serialization/deserialization (SerDes) chipsets that significantly lower the costs for automotive camera systems. Operating over standard coax cables, the MAX9273/MAX9272 (22 bits) and MAX9271/MAX9272 (16 bits) chipsets do not need the extra wires of an Ethernet setup to power a camera. With today's high-end automotive camera systems often using multiple cameras and cables, this coax solution represents a 50% reduction in cable and connectivity costs compared to current standard twisted-pair (STP) solutions.

Maxim's new camera chipsets operate at very high data rates (1.5Gbps), which is critical for today's fast video and megapixel image transmissions. Using coax cables, the chipsets do not need to compress data and thus process images immediately—a crucial requirement for safety applications like sign recognition, collision avoidance, and night vision. In comparison, Ethernet-based solutions require data compression, which requires external components, resulting in higher costs, power consumption, and power dissipation. The chipsets' reduced power consumption, from both the elimination of external components and low 75mA supply current, helps to prevent camera heat sensitivity issues. Finally, the coax cables on the chipsets are more robust than Ethernet cables; they provide better shielding, which reduces emissions and interference. Compared to solutions using Ethernet cables, the end result now is a cleaner, crisp image from the camera.

8400 HighLine Joins Lenze L-Force 8400 Inverter Drives for Motion Control

Lenze Americas, a leading global manufacturer of electrical and mechanical drives, motion control and automation technology, has launched the new 8400 HighLine Inverter Drives, part of the Lenze L-force 8400 portfolio. Designed for positioning applications, the HighLine model features integrated point-to-point positioning for up to 15 position destinations, and stores the corresponding travel profiles directly in the inverter. “Positioning in motor drive systems used to require a separate motion controller. Most applications don’t require a higher cost servo drive. Dynamic speed, torque and precision motion control can be achieved with a powerful inverter in combination with an asynchronous motor,” states Darrow Hanesian, director of inverter products, Lenze Americas. “Our streamlined HighLine delivers all the cost savings and benefits of combining two drive elements—the motion controller and the frequency inverter — into one.” The HighLine inverters’ integrated components transl...

Beko Oil-Vapour Monitor Gains TUV Certification Beko's Metpoint OCV oil-vapour monitoring system for chemical and pharmaceutical production processes has been certified by TUV Nord in accordance with the requirements of ISO 8573-1, Classes 1 to 4. According to the company, even 'oil-free' components give no guarantee for 'oil-free' compressed air, owing to the contamination of the ambient air/intake air. In most cases, a certain residual oil content cannot be entirely avoided in standard applications. The precise monitoring of the oil-vapour content, which is possible at any time, is important. In particular, in critical production processes in the chemical and pharmaceutical industry, in food production and surface coating, the analysis and control of compressed-air quality is a crucial factor, according to Beko. The network-compatible Metpoint OCV offers constant monitoring down to the range of a thousandth mg/m3 and features a touch-screen display and 24/7 pr...
