Long reach Industrial Ethernet chips for the last mile
The ADI Chronous ADIN1100 and ADIN1110 Industrial Ethernet PHY and MAC/PHY combo can transfer data over 1.7km

Analog Devices has launched a family of long-reach Ethernet chips to connect the edge to the cloud.

The latest Chronous devices support the 10BASE-T1L physical layer Ethernet standard allowing data streams from edge nodes in remote and hazardous locations across process and building facilities.

The ADIN1100 and ADIN1110 can transfer data over 1.7 kilometres or more than a mile through a single twisted pair of Ethernet cables, which helps reduce space, weight, and cost. These cables are lighter and more malleable than traditional Ethernet cables, and can support reuse of existing cabling infrastructure, reducing commissioning cost and complexity.

This enables data that was previously unavailable to be accessed across the network and used to assess factors such as asset health, raw material usage, and process parameters enabling cleaner manufacturing.

“Many process plants and buildings are struggling with constant manual local intervention required by service personnel and limited ability to optimise assets at an enterprise level,” said Mark Barry, General Manager of Automation and Energy at Analog Devices. “By providing long-reach Industrial Ethernet solutions that adhere to the 10BASE-T1L Ethernet standard, we’re making it possible for our customers to achieve reliable communications over much longer distances, covering the last mile in connectivity.  This truly enables the benefits of digitalisation through seamless access to edge data and improved control of remote assets.”

There are two options for the devices with a dedicated physical PHY part or combined MAC and PHY. The MAC PHY ADIN1110 simplifies retrofitting for Ethernet in field sensors or actuators and preserves existing investment in software and processor technology with a lower power of 42mW from a dual supply.

The ADIN1100 PHY provides standard Ethernet interfaces and supports use in more complex designs such as field switch developments or building controllers.
