About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

12-Channel LED Driver from Diodes Incorporated Enables Superior Performance for Digital Signage and Displays

Diodes Incorporated (Diodes) (Nasdaq: DIOD) today introduces a new 12-channel, constant-current LED driver, the AL58221. It features 12 open-drain outputs that are rated to 24V and sink up to 60mA of high-accuracy current with a fast transient response. The channel-to-channel LED current accuracy is typically ±1% and the regulated output current tolerance is ±0.1%.

Operating over a 3V to 5.5V input, the driver uses adaptive pulse density modulation (APDM) to help mitigate non-ideal IOUT distortion and enhance visual refresh rates for enhanced performance. It can be used for indoor and outdoor LED video signage and displays, variable messaging signs (VMS), architectural and decorative LED lighting systems, and LCD backlighting.

The AL58221’s LED current is set by three external resistors (for RGB master setting), with each channel’s average output current being programmed independently via its digital interface. It features a 10MHz double-edge triggered data clock input that reduces EMI. The device’s two-wire serial interface sends grayscale data to the function-control registers that store the configuration information. It controls grayscale resolution and clock frequency, current output waveform selection, and internal-latch function.

The driver uses APDM to increase the visual refresh rate of >1,000Hz at 16-bit and >256kHz at 8-bit grayscale. This technique reduces flicker and provides output-current bilateral processing for EMI reduction. The AL58221 uses a clock duty recovery technique with pulse retiming to support a longer distance connection. Its two-wire serial interface also enables cascading applications for up to 1,030 devices.

Within the same LED driver family, the recently introduced AL58263 is a 16-channel device with 16-bit PWM grayscale dimming control for higher resolution and larger display panel applications.

The AL58221 and AL58263 are available in the thermally enhanced TSSOP-24EP (Type A1-B) package at $0.37 and $0.47 respectively in 1,000-piece quantities.
