New AS22010 10GBASE-T PHY cuts power by 40% while improving cable reach, interference immunity, and network synchronization — enabling deterministic low-latency Ethernet connectivity for Wi-Fi 7 and Wi-Fi 8 access points, XGS-PON CPE, multi-gigabit enterprise edge, and modern AI infrastructure.

Aeonsemi (www.aeonsemi.com), an innovator of mixed-signal and DSP connectivity ICs, today announced production shipments of AS22010, the second generation of its ChronoPHY™ multi-rate 10GBASE-T Ethernet transceiver family. The AS22010 reduces typical per-port power by 40% compared to the previous generation while simultaneously improving link stability, electromagnetic interference (EMI) immunity, and synchronization accuracy to support ITU-T G.8273.2 Class D timing performance.

ChronoPHY™ is Aeonsemi’s Ethernet PHY architecture optimized for low-jitter and low-latency operation in time-sensitive networking applications such as wireless infrastructure, AI edge, industrial automation, and real-time Ethernet systems.

“AI is pushing high-speed Ethernet from the data center to the edge, where energy efficiency and deterministic timing are becoming increasingly critical,” said Yunteng Huang, CEO of Aeonsemi. “The AS22010 extends ChronoPHY™ leadership by delivering more precise synchronization, more robust connectivity, and a significantly smaller thermal footprint.”

Physical AI systems — including robots, machine vision platforms, and AI-enabled industrial automation infrastructure — increasingly require deterministic, low-latency, energy-efficient, high-speed Ethernet connectivity at the network edge. Built on the massive worldwide installed base of copper Ethernet infrastructure, multi-gigabit Ethernet adoption continues to accelerate due to its ease of deployment, high reliability, backward compatibility, and lower infrastructure upgrade costs.

Field-Proven ChronoPHY™ Architecture, Now with Lower Power and Enhanced Timing

The first-generation ChronoPHY™ established Aeonsemi as a leader in multi-rate copper Ethernet with long cable reach, robust noise immunity, and superior latency stability. The AS22010 further advances those capabilities with:

• 40% lower typical power at 10G/100 m compared with first-generation ChronoPHY™, enabling fanless Wi-Fi APs, quieter NAS enclosures, and higher-density multi-gigabit switches
• Enhanced Energy-Efficient Ethernet (EEE) operation across all supported rates, with faster wake and recovery behavior optimized for bursty AI and edge-network traffic patterns
• Enhanced SyncE + PTP timing functions, including an on-chip SyncE PLL to simplify system design in SyncE applications (AS22010J)

Purpose-Built for the Copper Edge of AI Infrastructure

Wi-Fi 7 access points require multi-gigabit backhaul to deliver their tri-band aggregate throughput, and Wi-Fi 8 will further increase backhaul bandwidth requirements. NAS platforms running local inference, multi-gigabit switches, and AV-over-IP systems are converging on the same 10GBASE-T port. At the same time, AI-enabled edge infrastructure increasingly depends on deterministic timing, lower power consumption, and always-on connectivity. The AS22010 addresses these requirements by combining deterministic 10Gbps connectivity, power efficiency, and advanced timing capabilities.
