Santa Clara, Calif. – September 22, 2026 -- Aeonsemi, Inc. has introduced the Praxium PHY family, a line of multi-gigabit Ethernet transceivers delivering data rates up to 10 Gbps in a 6 x 6 mm QFN package for robots, autonomous vehicles and industrial machines.
Praxium cuts power to as low as 350 mW for 10 Gbps sensor links
The chips support IEEE 802.3ch standards for 10GBASE-T1, 5GBASE-T1 and 2.5GBASE-T1 operation, and use Energy-Efficient Ethernet on lower-speed uplinks to reach the 350 mW figure for asymmetric 10 Gbps connections. The family targets cameras, LiDAR, zone controllers and network backbones inside Physical AI systems where component size and power budgets are constrained.
Four devices cover single- and multi-port sensor, converter and backbone use cases
The lineup includes the AS31010 (single-port 10G/5G/2.5G), AS31510 (single-port 5G/2.5G), AS31210 (single-port 2.5G) and AS31040 (quad-port 10G/5G/2.5G), giving system designers PHY options across sensor nodes, media converters and backbone links.
Expanded cabling support adds coax and mini-twinax beyond shielded twisted pair
Beyond IEEE 802.3ch-compliant shielded twisted pair operation, Praxium PHYs add coax and miniature twinax cabling options, along with Power over Coax and Power over Data Lines support. Aeonsemi says this lets engineers optimize cable weight, diameter, routing and EMC performance through space-constrained mechanical joints while keeping a single Ethernet architecture from distributed sensors to central compute.
CEO says reduced footprint makes multi-gigabit Ethernet viable for humanoid robots
"With Praxium, we have dramatically reduced the power and footprint required to deploy that technology while expanding the cabling options available to system designers,
