Manufacturers, power utilities and other industrial companies stand to gain the most in digital transformation. Manufacturing and construction industries account for 37 percent of total energy used globally*, for instance, more than any other sector. By fine-tuning operations with AI, some manufacturers can reduce carbon emission by up to 20 percent and save millions of dollars in the process.
Industry, however, remains relatively un-digitized and gaps often exist between operational technology – the robots, furnaces and other equipment on factory floors—and the servers and storage systems that make up a company’s IT footprint. Without that linkage, organizations can’t take advantage of Industrial Internet of Things (IIoT) technologies, also referred to as Industry 4.0. Of the 232.6 million pieces of fixed industrial equipment installed in 2020, only 10 percent were IIoT-enabled.
Why the gap? IT often hasn’t been good enough. Plants operate on exacting specifications. Engineers and plant managers need a “live” picture of operations with continual updates on temperature, pressure, power consumption and other variables from hundreds, if not thousands, of devices. Dropped, corrupted or mis-transmitted data can lead to unanticipated downtime—a $50 billion year problem—as well as injuries, blackouts, and even explosions.
To date, getting around these problems has required industrial applications to build around proprietary standards and/or complex component sets. These systems work—and work well—but they are largely cut off from the digital transformation unfolding outside the factory walls.
The new Prestera® DX1500 switch family is aimed squarely at bridging this divide, with Marvell extending its modern borderless enterprise offering into industrial applications. Based on the IEEE 802.1AS-2020 standard for Time-Sensitive Networking (TSN), Prestera DX1500 combines the performance requirements of industry with the economies of scale and pace of innovation of standards-based Ethernet technology. Additionally, we integrated the CPU and the switch—and in some models the PHY—into a single chip to dramatically reduce power, board space and design complexity.
Done right, TSN will lower the CapEx and OpEx for industrial technology, open the door to integrating Industry 4.0 practices and simplify the process of bringing new equipment to market.

The way in which data is moved via wireline and wireless connectivity is going through major transformations. The dynamics that are causing these changes are being seen across a broad cross section of different sectors.
Within our cars, the new features and functionality that are being incorporated mean that the traditional CAN and LIN based communication technology is no longer adequate. More advanced in-vehicle networking needs to be implemented which is capable of supporting multi-Gigabit data rates, in order to cope with the large quantities of data that high resolution cameras, more sophisticated infotainment, automotive radar and LiDAR will produce. With CAN, LIN and other automotive networking technologies not offering viable upgrade paths, it is clear that Ethernet will be the basis of future in-vehicle network infrastructure - offering the headroom needed as automobile design progresses towards the long term goal of fully autonomous vehicles. Marvell is already proving itself to be ahead of the game here, following the announcement of the industry’s first secure automotive gigabit Ethernet switch, which delivers the speeds now being required by today’s data-heavy automotive designs, while also ensuring secure operation is maintained and the threat of hacking or denial of service (DoS) attacks is mitigated.
Within the context of modern factories and processing facilities, the arrival of Industry 4.0 will allow greater levels of automation, through use of machine-to-machine (M2M) communication. This communication can enable the access of data — data that is provided by a multitude of different sensor nodes distributed throughout the site. The ongoing in-depth analysis of this data is designed to ultimately bring improvements in efficiency and productivity for the modern factory environment. Ethernet capable of supporting Gigabit data rates has shown itself to be the prime candidate and it is already experiencing extensive implementation. Not only will this meet the speed and bandwidth requirements needed, but it also has the robustness that is mandatory in such settings (dealing with high temperatures, ESD strikes, exposure to vibrations, etc.) and the low latency characteristics that are essential for real-time control/analysis. Marvell has developed highly sophisticated Gigabit Ethernet transceivers with elevated performance that are targeted at such applications.
Within data centers things are changing too, but in this case the criteria involved are somewhat different. Here it is more about how to deal with the large volumes of data involved, while keeping the associated capital and operational expenses in check. Marvell has been championing a more cost effective and streamlined approach through its Prestera® PX Passive Intelligent Port Extender (PIPE) products. These present data center engineers with a modular approach to deploy network infrastructure that meets their specific requirements, rather than having to add further layers of complexity unnecessarily that will only serve to raise the cost and the power consumption. The result is a fully scalable, more economical and energy efficient solution.
In the wireless domain, there is ever greater pressure being placed upon WLAN hardware - in the home, office, municipal and retail environments. As well as increasing user densities and overall data capacity to contend with, network operators and service providers need to be able to address alterations that are now occurring in user behavior too. Wi-Fi connectivity is no longer just about downloading data, increasingly it will be the uploading of data that will be an important consideration. This will be needed for a range of different applications including augmented reality gaming, the sharing of HD video content and cloud-based creative activities. In order to address this, Wi-Fi technology will need to exhibit enhanced bandwidth capabilities on its uplink as well as its downlink.
The introduction of the much anticipated 802.11ax protocol is set to radically change how Wi-Fi is implemented. Not only will this allow far greater user densities to be supported (thereby meeting the coverage demands of places where large numbers of people are in need of Internet access, such as airports, sports stadia and concert venues), it also offers greater uplink/downlink data capacity - supporting multi-Gigabit operation in both directions. Marvell is looking to drive things forward via its portfolio of recently unveiled multi-Gigabit 802.11ax Wi-Fi system-on-chips (SoCs), which are the first in the industry to have orthogonal frequency-division multiple access (OFDMA) and multi-user MIMO operation on both the downlink and the uplink.

The semiconductor industry is witnessing exponential growth and rapid changes to its bandwidth requirements, as well as increasing design complexity, emergence of new processes and integration of multi-disciplinary technologies. All this is happening against a backdrop of shorter development cycles and fierce competition. Other technology-driven industry sectors, such as software and hardware, are addressing similar challenges by creating open alliances and open standards. This blog does not attempt to list all the open alliances that now exist -- the Open Compute Project, Open Data Path and the Linux Foundation are just a few of the most prominent examples. One technological area that still hasn’t embraced such open collaboration is Multi-Chip-Module (MCM), where multiple semiconductor dies are packaged together, thereby creating a combined system in a single package.
The MCM concept has been around for a while, generating multiple technological and market benefits, including:
Sub-dividing large semiconductor devices and mounting them on an MCM has now become the new printed circuit board (PCB) - providing smaller footprint, lower power, higher performance and expanded functionality.
Now, imagine that the benefits listed above are not confined to a single chip vendor, but instead are shared across the industry as a whole. By opening and standardizing the interface between dies, it is possible to introduce a true open platform, wherein design teams in different companies, each specializing in different technological areas, are able to create a variety of new products beyond the scope of any single company in isolation.
This is where the USR Alliance comes into action. The alliance has defined an Ultra Short Reach (USR) link, optimized for communication across the very short distances between the components contained in a single package. This link provides high bandwidth with less power and smaller die size than existing very short reach (VSR) PHYs which cross package boundaries and connectors and need to deal with challenges that simply don’t exist inside a package. The USR PHY is based on a multi-wire differential signaling technique optimized for MCM environments.
There are many applications in which the USR link can be implemented. Examples include CPUs, switches and routers, FPGAs, DSPs, analog components and a variety of long reach electrical and optical interfaces. Figure 1: Example of a possible MCM layout
Marvell is an active promoter member of the USR Alliance and is working to create an ecosystem of interoperable components, interconnects, protocols and software that will help the semiconductor industry bring more value to the market. The alliance is working on creating PHY, MAC and software standards and interoperability agreements in collaboration with the industry and other standards development organizations, and is promoting the development of a full ecosystem around USR applications (including certification programs) to ensure widespread interoperability.
