Marvell PHYs for Low-Latency Industrial Ethernet

By Kaushik Mittra

Part 1 of Two-Part Series

Introducing the Marvell 88E1510P/1512P/1510Q Family of PHY Products

Traditionally Ethernet has been used in enterprise applications – we are familiar with its use in our office environments. But the IEEE 802.3 family of standards is constantly evolving. Industrial networks present their own set of challenges, and Ethernet with its components are evolving again to address the needs of the factory floor. Connectivity hardware that can offer low-latency, enhanced electrostatic discharge (ESD) protection while operating in extended temperature environments is invaluable to industrial network implementation. The Marvell 88E1510P/88E1512P/88E1510Q family of PHY (physical layer device) products was designed from the ground up in collaboration with leaders in industrial automation and has been vetted for use in the most demanding industrial applications.

A multitude of communication protocols are used in industrial networks today including EtherNet/IP, EtherCAT, Profinet and SERCOS III. These are independent and proprietary offerings from different vendors. But what they share in common is the goal to deliver real-time Ethernet to industrial automation applications under harsh environmental conditions. The typical elements of an industrial network might include programmable logic controllers (PLCs), motor controllers and drives, sensor networks and human machine interfaces (HMIs). These elements are connected on the Ethernet backbone using a protocol such as EtherCAT or Profinet. The network topology might be hub-spoke (star) or linear. Regardless of network topology, the goal is to provide precise control and synchronized timing information to each of the nodes. If the topology is a long daisy chain, then each node has to perform with the most optimized latency to enable fast request/response cycle times through the system.

Figure1-IndustrialConnectivity

Looking for a Low-Latency PHY?

Protocols such as EtherCAT have to process the Ethernet packet and insert new data into the frame as it passes through in real-time. For real-time applications, this imposes tight restrictions on the latency through the switch and PHY. With this requirement in mind, we designed the Marvell 88E1510P/1512P/1510Q family of PHY products to address the stringent latency needs of tier-1 industrial customers. The table below shows that the Marvell low-latency PHY operates 30-40 percent faster as compared to non-optimized implementations.

Figure2-Default-transmit

While the data shown above is the default configuration, significantly lower latencies are possible with register programming. The sum total of transmit and receive latency was less than 400ns across the entire range, as shown below.

Figure3-Lessthan400ns

The small latency variation observed (from min to max) is due to the presence of synchronization circuits in the transmit path. Typically a FIFO (first in, first out queue) is used in the transmit path to compensate for any PPM (parts-per-million) differences between the transmit circuits and receiving circuits. Depending on packet size and the number of entries in the FIFO, a small variation in latency can be observed.

(Note: When the PHY is used for precision-time protocol- (PTP-) based timestamping applications, the presence of the FIFO does not affect the accuracy of the timestamps. The timestamps are taken closest to the wire, eliminating the FIFO uncertainty).

Future Proof with 1000BASE-T

While 100BASE-TX speeds are sufficient for the majority of factory applications today, there is a growing need to support 1000BASE-T. Since the installation of industrial equipment and networks is capital-intensive, it is prudent to use a PHY device that can future-proof network speed requirements up to 1000BASE-T. The Marvell 88E1510P/1512P/1510Q family of PHY products supports 10BASE-T, 100BASE-TX, and 1000BASE-T. The low latency ranges observed in 1000BASE-T mode is shown below.

Figure4-Lessthan400ns

Extended Temperature Operation and ESD support

In an industrial environment, it is difficult to control temperatures on the plant floor, where surrounding equipment may operate at high temperatures and where it can be difficult to provide good ventilation. Industrial motors and robots connected by an Ethernet network often have to weld metals at very high temperatures.

Figure5-Ethernetcomponents-
This requires the PHY to operate in environments where the ambient temperature remains high throughout the entire duration of operation (for more than several hours). The Marvell 88E1510P/1512P/1510Q family of PHY products was designed to operate in ambient operating temperature ranges of minus -40 0C to 85 0C degrees (or 125 0C maximum junction temperature.)

In addition to high temperature, industrial environments can also lead to accumulation of electric charge within the machinery. To shield against high voltage surges, the Marvell PHY has enhanced ESD protection circuits. We tested the Marvell PHY in the robust testing environments of some of the largest industrial electronics OEMs who approved the device from an ESD perspective.

Packaging and Interface Options

The Marvell 88E1510P/1512P/1510Q family of PHYs is offered in 48-pin or 56-pin QFN packages. It also offers a variety of host interface options such as RGMII, MII and SGMII. For information on specific features, please review the attached product selector guide.

In conclusion, connectivity hardware that can offer enhanced ESD protection, low-latency and operate under extended temperature ranges is gaining popularity in industrial networks. The Marvell 88E1510P/1512P/1510Q family of PHYs offers these key benefits to implement in any real-time industrial Ethernet network.

Marvell Delivers Industry’s First IEEE Gigabit Ethernet For Automotive

By Anil Gercekci

High-Speed Networking Becomes a Reality For Automotive
Creating New Consumer Features

Marvell First to Deliver Samples to Auto Manufacturers

With the availability of high-speed LTE networks and the thrust toward autonomous driving, car companies are working on a structured approach to high-speed data distribution to and within vehicles. Today, Gigabit Ethernet over a single pair of twisted-pair copper wire has become a reality for the automotive industry paving the way for high-speed networking within a vehicle. In November of last year, Marvell delivered the first samples based on the IEEE 1000BASE-T1 pre-standard specification for verification of performance in vehicles. The 1000BASE-T1 standard allows high-speed and bi-directional data traffic over light-weight, low-cost, single-pair cable harnesses. This enables car companies to create a whole new array of exciting automotive features and benefits. Early chip samples from Marvell allow auto makers the ability to evaluate the performance of this new standard and identify possible issues early in the application development process, prior to production, to accelerate time to market.

Industry Standards Organizations Paving the Way to Seamless Automotive Wireless Communications

Simultaneously, a number of industry standards organizations are working on automotive-specific wireless standards that will enable seamless internal and external communications with vehicles to enable cloud-based applications. With LTE standards enabling higher than 100Mbps data capability, LTE connectivity will require high-speed links in line with 100BASE-T1 or 1000BASE-T1 Ethernet capabilities within the vehicle, depending on the actual real throughput available to the user from the network. As carrier network coverage and data billing rates become accepted by consumers, cloud-based applications for automotive will allow large data transfers that will enable not only wider infotainment, but concierge and navigation applications, plus remote diagnostics with secure over-the-air (OTA) updates. (Won’t it be nice to know when you’re pulled over on the side of the highway on vacation, exactly what is wrong with your car?) Such mechanisms will also enable security and accelerated fleet management for business and commercial enterprises that can help lower the cost of maintenance, while increasing customer satisfaction by keeping drivers up-to-date with the latest cloud-based data services.

A History of Firsts

Marvell has a history of actively participating in the IEEE standards development process. In 2011, Marvell was a key driver in the Call For Interest (CFI) at IEEE for an Automotive-specific Gigabit Ethernet PHY. This CFI received unanimous support (a relatively rare event in IEEE) and now the new IEEE 802.1bp standard is set to be ratified in 2016. In the meantime, Marvell has already begun sampling pre-standard parts to the industry for testing. The availability of parts has sparked remarkable interest and activity in testing and developing new applications for high-speed Ethernet.

Will Automotive Become the Largest IT Employer In the Near Future?

The introduction of Automotive-specific Gigabit Ethernet can provide the backbone for enhanced connectivity applications. The automotive industry is rapidly adopting Ethernet as a key enabler, not only for its superior price/performance, but also because it supports the Open Systems Interconnection (OSI) model. The OSI model allows for the rapid deployment of applications and services. Using this layered approach, a specific PHY technology, which met both the light weight and low EMC requirements, had to be developed that was consistent with all the existing upper layers of the OSI model. This gives the benefits of being able to leverage and reuse existing developments in layers above the PHY level. It is amazing to think that with this unprecedented potential expansion of automotive connectivity and its applications, it is conceivable that the automotive industry could become the world’s largest employer of IT experts in the coming years.

More to Come
In addition to a long history of WiFi and Bluetooth combo products in automotive, Marvell is enabling WiFi technology to become part of this external connectivity by developing 802.11ai technology that allows for Fast Initial Link Setup (FILS) that provides opportunistic access to base stations whenever they become available as the car drives at high speed. In addition, 802.11p products will enable short-range wireless connectivity for collision avoidance or pedestrian/cyclist detection, applications that demand quick response and are not possible via current Light Detection and Ranging (LIDAR) and LTE technologies. With these wireless technologies placed in the roof of the car, Ethernet plays an important role for high-speed communication to and within the vehicle. By delivering early samples based on the latest developing industry standards, Marvell is helping to “drive” new applications in automotive connectivity technology.

NO DEAD ZONES: New Home Networking Products, Based on Marvell G.hn Powerline Technology, Redefine the Home Wi-Fi Experience

By Donna Yasay

You’ve seen it, the dreaded buffering while trying to stream a movie, lag times while gaming or dropped signals as you walk through your home. In fact, you probably know exactly where the dead zones are in your house.  But all this is a thing of the past with the latest products based on Marvell’s Gigabit Home Networking (G.hn) Powerline Communications technology. Marvell G.hn chip sets combine powerline, coax, phone line/twisted pair and optical fiber in a single technology, which can turn a home’s electrical, coaxial and anywire smart grids into high-speed internet and connected devices.

ArrisSURFboard

Take for example the new line of ARRIS routers and extenders, the SURFboard® family of home networking devices with RipCurrent™ G.hn technology.  This new system of routers and extenders, based on Marvell technology, is designed to eliminate the frustrations that have plagued home wireless as more and more family members use more and more devices.  The RipCurrent-enabled routers and extenders use existing powerlines (electrical outlets) in the home to create new hotspots to connect high-bandwidth devices and relieve home Wi-Fi congestion.

ARRIS SURFboard is an easy-to-set up device that can bring gigabit speeds to every room, not just the room nearest to the router.  That means ultrafast Wi-Fi in any room, sharing one internet connection.  Range is no longer an issue and interruptions become non-existent. Now, mom can binge-watch her favorite program, while the teens are gaming or streaming, without suffering the dreaded buffering lag times.  (Where’s dad? He’s shopping the internet for more cool devices.)

And while ARRIS International plc was the top cable modem retailer in 2016, they aren’t the only ones where Marvell G.hn Powerline is playing an integral role. Last summer, Comtrend, a leading designer and manufacturer of broadband communication equipment, launched its first G.hn powerline-only adapter in retail.

COMTREND

G.hn offers the flexibility of providing high bandwidth for in-home networking using both a wired medium and wireless extender setting.  Offering full home connectivity at 1 Gbps and 2 Gbps PHY rates, Marvell G.hn chipsets represent an ideal solution for wireline distribution of bandwidth-intensive and real-time applications like HD-IPTV, VoIP, gaming, video surveillance, multi-room DVR and more. The new 2Gbps chipset offers support for the new ITU-T G.hn 200MHz channel bandwidth, allowing for higher data transmission rates through the multitude of supported connections that G.hn already offers. Marvell’s 2 Gbps G.hn chipsets will enable vendors to build a new generation of solutions for wired IPTV delivery and 802.11ac extenders that will double the throughput and increase the range of existing products.

With no more dead zones, Marvell G.hn powerline technology is helping redefine home networking and improving the home Wi-Fi experience.

How Marvell FLC Redefines Main Memory

By Hunglin Hsu

With newer, bigger programs and more apps multitasking simultaneously, the answer to making any system run faster, from handheld to super computer, was always just to add more DRAM. . . and more, and more and more. Well, those days will soon be “memory” with Marvell’s introduction of Final-Level Cache™ (FLC™). FLC is an architecture that redefines memory on everything from data centers to wearables. By offloading the storage of programs to less expensive solid-state drives (SSDs) and only using a small amount of expensive DRAM to cache the active processes, the amount of DRAM can be cut dramatically along with power consumption.  FLC has the potential to spark the development of a new class of lower-cost and lower- power products and cut the DRAM needed in a system by as much as 10x, while cutting the energy consumed to about half what is used today.

FLC-solution-003

How? If you look at what’s actually being used on your computer or portable device, only a small percentage of the application code loaded into the main memory is usually active. Take a look for yourself. For example, look at the process monitor in Windows task manager. You will see that most of the applications are idle, yet in aggregate require a significant amount of DRAM space. In fact, nearly 90 to 99 percent of most DRAMs are idle. By using a special algorithm, Marvell FLC can put the most frequently used programs on a small amount of DRAM and the rest onto less expensive, energy-efficient flash memory that can reduce the size, cost and power requirements of anything from a smart car, to mobile phones, tablets, smart watches, computers or data centers.

And it works!  Our engineering mobile phone platform, shown in this video, uses FLC to play back video smoothly, without any lag or stutter.  App switching is also zippy.  Such performance is common on mid- or even high-end phones with large DRAM, yet this design used only 768MB of DRAM in the implementation.  Time-sensitive streams are mapped to a 512MB non-cacheable area, while another 256 DRAM is used in FLC to emulate 1GB of memory. Hence, it provides similar performance to 1.5GB of main memory in traditional DRAM-based designs. FLC can also emulate larger quantities of main memory.  The second proof of concept demonstrates smooth video performance on the same mobile phone platform using FLC.

With FLC, better performance can be achieved by reporting to the operating system a larger than physically implemented main memory. The operating system is thus less likely to kill background apps, which is why the fast app switching is possible. The FLC hardware does all the heavy lifting in the background and frees up the tasks of the operating system.

Smaller DRAM means less power and lower cost creating endless new possibilities. It will free up innovation in digital design and even accelerate categories like the Internet of Things (IoT.)  By offloading storage to cheaper SSD memory, the world can also dramatically reduce overall power consumption and energy needs. For example, a 50 percent reduction in all computer energy use equates to a two percent decrease in rural power needs. Battery life of laptops will be increased, as well as IoT devices that could last weeks before recharging. It changes the future of supercomputers as well. With FLC, you can replace an entire server room with a small portable device. Super computing and computational sets will become faster and more efficient, with future super computers containing tens of terabytes of memory instead of hundreds of gigabytes. Data center space savings and cooling costs will also be dramatically reduced.

This is why Marvell Final-Level Cache represents a monumental technical step forward. Marvell FLC will not only redefine memory–but all of computing.

Social-Local-Mobile Wi-Fi is Here New Wi-Fi CERTIFIED Wi-Fi Aware Adds Proximity-Based, Peer-to-Peer Services

By Jawad Haider

Have you ever been in a situation where you went out with your family or group of friends/colleagues to a crowded venue (think picnic, movies, trade show, shopping mall) and you ended up getting separated? You tried calling and texting each other, but the network was congested. You even thought of sharing your location via WhatsApp, but there wasn’t an Internet connection for that to happen!  You couldn’t help feeling, “If only wireless connectivity could be easier!”

The new Wi-Fi CERTIFIED Wi-Fi Aware™, announced July 14 by the Wi-Fi Alliance, has a solution for that problem. Mobile devices are about to become truly “local” and “social.” What that means is that all mobile devices which are Wi-Fi Aware-capable will be able to discover each other and initiate “interactions” with each other in a pure peer-to-peer fashion. By interactions, I mean services and applications that we already use today on our phones like social networking, gaming, maps, VOIP chat, targeted ads and coupons. All these applications today need some form of Internet connectivity in order to run. Wi-Fi Aware provides for a mechanism for users to initiate interactions with people and services in their “proximity” without the need to be connected to a Wireless Access Point. Common examples might include friend-finder, social gaming, walkie-talkie or a product locater inside a marketplace.

wifi-aware

Wi-Fi CERTIFIED WI-FI Aware is a new certification program for a new capability of Wi-Fi previously known as “Neighbor Awareness Networking” (NAN). Wi-Fi Aware enables a unique peer-to-peer technology that does not require real-time connection to a Wi-Fi infrastructure, server, GPS or other geo-location, but instead uses direct device-to-device Wi-Fi to discover and exchange information. It enables devices to discover nearby information and services before even making a connection. Wi-Fi Aware makes social/local/mobile applications more useful and personalized, and works well in crowded environments. It is designed for power efficiency.

Marvell demonstrated sample NAN capabilities earlier this year at Mobile World Congress. The demo was used in the context of a navigation application, which traditionally has huge challenges operating indoors. Using two Marvell-powered smartphones, one user could discover his nearby colleague and use the mapping application via a Wi-Fi Direct connection to navigate right to him.

Wi-Fi™ Aware extends Wi-Fi’s capabilities with a real-time, energy-efficient discovery mechanism that will allow a multitude of proximity-based applications.  The Marvell Avastar family of wireless connectivity chipsets supports the Wi-Fi Alliance NAN Specification and we hope to be Wi-Fi Aware-certified soon.  In fact, Marvell’s recently announced Avastar Marvell 88W8997 chipset already supports the industry’s most advanced connectivity feature sets including 802.11mc, an IEEE standard for precise indoor location; BLE Angle of Arrival/Angle of Departure based on Bluetooth SIG standards and Multi-User MIMO for robust wireless connectivity. These advanced features, combined with Wi-Fi Aware, will allow our customers to build exciting new products and enable application developers to add a whole new dimension to how mobile devices interact with each other. This will open the door to truly Social & Local mobile applications. So with the new Wi-Fi Aware, if you aren’t sure where you want to go next, I’m sure there will be an app right around the corner that will help you.
