Wilmington, MA / Munich, Germany. Analog Devices, Inc. revealed its 5-port LTC4296-1 and LTC9111  solution for single-pair Power over Ethernet (SPoE), Power Sourcing Equipment (PSE), and Power Device (PD).  Analog Devices’ SPoE platforms focus on obstacles facing the supply of energy and data transmission (over one kilometer) to edge devices including asset health, environmental conditions, and security metrics.

Polarity Corection is supported by both SPoE and Power over Data Line (PoDL) variants of single-pair powering. while the SPoE also provides interoperable point-to-point power solutions, up to 52W. The LTC4296-1 and LTC9111 are 802.3cg compliant and  Serial Communication Classification Protocol (SCCP) enabled.

“The Intelligent Edge is one of the most exciting developments of the digital era as computing power is pushed to previously inaccessible applications and locations,” said Leo McHugh, Vice President of Industrial Automation at Analog Devices. “Analog Devices is committed to delivering the unrivaled technology and solutions our customers need to leverage the full potential of the Intelligent Edge in smart buildings and factories as well as many more applications in the future.”
