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.

3.3V, Quad-Channel, Hybrid ReDrivers from Diodes Incorporated Enable HDMI 2.1 Signal Integrity for High-Resolution Video Transmission

Diodes Incorporated (Nasdaq: DIOD) today introduces two 3.3V, quad-channel, hybrid ReDrivers™ with integrated display data channel (DDC) listeners designed to enhance signal integrity for HDMI applications and simplify system designs. The PI3HDX12311 caters to high bandwidth applications up to 12Gbps for HDMI 2.1 fixed rate link (FRL) and transition-minimized differential signaling (TMDS) up to 6Gbps. The PI3HDX6311 supports HDMI 2.0 at 6Gbps. The devices also support DisplayPort™ Dual-Mode (DP++) V1.1 level shifting.

The products act as an intermediary between a source (like a CPU or GPU) and a sink (like a display), compensating for signal degradation over transmission lines. The devices are suitable for applications in laptop and desktop PCs, docking stations, peripheral devices, gaming consoles, DTV and commercial display panels, and HDMI active cables.

Both are hybrid devices that operate in either limited or linear mode. For HDMI 1.4 applications, the devices operate as limited ReDrivers, where the differential output swing is pre-defined by the swing setting to ensure HDMI-compliant levels at the receptacle. In contrast, for HDMI 2.0 and 2.1 applications, they function as linear ReDrivers, where the output swing is directly proportional to the received signal, effectively acting as a trace canceller. This linear mode is inherently transparent to the link training signals, and for the PI3HDX12311, enables 8K DTV video resolution and data rates up to 48Gbps (12Gbps per channel).

The devices allow for AC or DC coupling of the input and output signals, or a mixture of both, with short-circuit detection in DC coupled mode. Both devices also utilize pin-strapping control for operation mode, equalization, flat-gain, output swing, and output -1dB linearity swing. The devices share features like auto selection of TX settings, IOFF support, and far-end receiver detection.

To minimize power consumption, the PI3HDX12311 and PI3HDX6311 monitor the hot-plug-detect (HPD) pin in the connector to control power consumption and enter a low-power state if the HPD is low for more than 2ms. Their DDC listeners function similarly by snooping the HDMI Forum Vendor Specific Data Block (HF-VSDB) and monitoring the same Status and Control Data Channel Structure (SCDCS) offset registers.

The PI3HDX12311 and PI3HDX6311 are available in the tiny 32-pin X1‑QFN2845 package, occupying a 2.85mm x 4.5mm PCB area, and operate across the -40°C to +70°C temperature range with 726mW (typ.) power dissipation. The hybrid ReDrivers are available at $0.99 [PI3HDX12311] and $0.77 [PI3HDX6311] in 3,500-piece quantities.
