Industrial Ethernet Physical Layer Devices

The ADI Chronous Industrial Ethernet physical layer (PHYs) portfolio includes solutions for standard 10 Mbps, 100 Mbps, and 1 Gbps. It also features the new 10BASE-T1L technology for single-pair Ethernet.

Our industry-leading low latency and low power PHY technology maximizes data transmission and signal integrity in deterministic applications by reducing cycle times and system power consumption. It enables superior synchronization of signals across the industrial network and supports the development of TSN.

This portfolio of ultra low power 10BASE-T1L products includes both PHY and MAC PHY solutions to support optimization of system power budgets while offering flexibility in design choice. The unique MAC PHY technology enables the reuse of existing low power processor technologies that do not support traditional Ethernet interfaces, and instead enable connection via SPI.

Having completed extensive EMC and robustness testing, ADI Chronous PHY products are ideally suited for applications demanding predictable and secure communications. Designed to operate over an extended industrial ambient temperature ranges, Industrial Ethernet physical layer devices provide the highest level of reliability for the Industrial Ethernet applications of today and tomorrow.

What Is 10-BASE-T1L?

The IEEE 802.3cg-2019 standard governs 10BASE-T1L connectivity. It is a single-pair Ethernet (SPE) media standard, providing for 10 megabits per second communication and enabling both power and data over single twisted pair cabling up to 1 km.

10BASE-T1L physical layer transceivers, part of the ADI Chronous portfolio, will enable Ethernet connectivity to edge nodes and direct IP addressability. Our technology enables the communication of new insights about process variables or building parameters to control systems. This will enable the optimization of asset utilization in process control and drive building management efficiencies.

Lower Cost Single Twisted Pair Cabling

Lighter, lower cost, and smaller size than standard CATx cables, these cables are also often easier to install. 10BASE-T1L technology will enable the reuse of some existing single twisted pair cabling infrastructure.

Long 1 km Reach

Field sensors are often deployed in remote locations, and existing Ethernet physical layer technologies are typically limited to 100 meters. The longer transmission distance enables longer distance device connectivity.

Power and Data on Two Wires

Field sensors require power, and the ability to deliver power over the cable is critical for remote locations. The standard helps deliver up to 500 mW of power within intrinsically safe applications and 60 W within non-intrinsically safe applications. This is cable dependent.

New Data, New Insights with 10BASE-T1L

Long reach, single-pair Ethernet, 10BASE-T1L physical layer devices are proving a game changer on the road to realizing the Industry 4.0 vision of seamless connectivity. By extending Ethernet connectivity to edge nodes in remote and distant locations, this technology enables new data streams, additional process variables, and auxiliary measurements to be communicated.

What Is an Industrial Physical Layer Device (PHY)?

An Industrial Ethernet PHY is a physical layer transceiver device for sending and receiving Ethernet frames based on the OSI network model. In the OSI model, Ethernet covers Layer 1 (the physical layer) and part of Layer 2 (the data link layer) and is defined by the IEEE 802.3 standard. The physical layer specifies the types of electrical signals, signaling speeds, media and connector types, and network topologies. It implements the Ethernet physical layer portion of the 1000BASE-T (1000 Mbps), 100BASE-TX (100 Mbps over copper), and 10BASE-T (10 Mbps) standards.

The data link layer specifies how communications occur over the media as well as the frame structure of messages transmitted and received. This simply means how the bits come off the wire and into a bit arrangement so the data can be extracted from the bit stream. For Ethernet, this is called media access control, or MAC for short.

Key Considerations When Selecting an Industrial PHY

In automation applications for Industrial Ethernet physical layer devices, there are a few critical features required to ensure high reliability and network resilience.

The network cycle time is the communication time required by the controller to both collect and update the data memories of all devices. A low latency PHY reduces network cycle time, improving network refresh time and allowing more devices to be connected to the network.

Built to withstand external radiated and conducted noise sources given the harsh operating environment. Select products have been tested and adhere to EMI/EMC standards like CISPR 32 and IEC 61000-4-2 through IEC 6100-4-6. This robustness helps prevent lengthy redesign cycles to secure certification later in the development flow.

Low Power

Devices for industrial applications are typically IP65/IP66 sealed from dust and moisture and, hence, have restricted airflow and limited power dissipation capability. Similarly, these devices are often exposed to high ambient temperature in industrial environments. Because line and ring topologies require two ports and two PHYs, power dissipation is doubled for data in and out.
