Support powerline communications with one modem

16 June 2015

Maxim Integrated’s ultra-low-power PLC modem reduces footprint by up to 3x and improves time to market.

Powerline communication standards and frequency bands vary by region and country, and until now PLC modems could not support them all. Meter manufacturers had to develop multiple modems to ensure standards compatibility, or even pass up markets because they did not have the time or resources to develop new modems. That dilemma is now solved. The ZENO/MAX79356 PLC modem SoC is software configurable to accommodate all worldwide standards. Now manufacturers and utilities can use the same device to build meters and data concentrators for any region that wants to use powerline communication. This allows meter designers to bring their products to market faster and be prepared for future standards. In addition, the integration of the analogue front-end (AFE) and baseband in a single chip reduces chip count and lowers expenses. 

Key advantages

• Versatile: software configurability supports today’s PLC standards and will adjust for future standards; certified by the G3-PLC Alliance for all three major frequency bands (CENELEC A, ARIB, and FCC) and for PAN Device and PAN Coordinator.
• Low power: uses 80% less power when listening for PLC communication (55mW vs. 300mW); active transmission power consumption is 70mW. 
• Space efficient: up to 3x smaller than other PLC modems.


“Maxim is leveraging its G3-PLC leadership to become a reference for all standards around the world,” said Kris Ardis, Executive Director, Energy Solutions at Maxim Integrated. “We listened to our customers and have solved their current and long-term PLC concerns with ZENO.”

“While we expect narrowband PLC to stand out as a fast-growing communications technology over the next few years, we don’t see consolidation of the standards and frequency bands requested by utilities,” said Jacob Rodrigues Pereira, Senior Analyst, Smart Utility Infrastructure at IHS. “Solutions like the MAX79356 will make it easier for meter manufacturers to support multiple markets without increasing their development costs.” 


The MAX79356 is available now at Maxim's website and select franchised distributors.
