Microchip Introduces Optical Ethernet PHY Transceivers with Integrated PTP and MACsec for Extended-Distance Networking

Manufacturing-News

As industries increasingly rely on connected systems—from smart factories and remote operations to intelligent infrastructure—the need for high-performance, long-range, and secure networking solutions continues to grow. Addressing this demand, Microchip Technology Inc (Nasdaq: MCHP) has unveiled a new series of Optical Ethernet PHY transceivers, available in 25 Gbps and 10 Gbps options, featuring built-in IEEE® 1588 Precision Time Protocol (PTP) and Media Access Control Security (MACsec) encryption.

These new optical transceivers deliver a deterministic, secure, and scalable networking option compared to traditional copper-based Ethernet. Supporting transmission distances of up to 10 kilometers over single-mode fiber, they are ideal for large-scale environments such as industrial sites, campuses, and logistics hubs. The integrated PTP timestamping offers sub-nanosecond (<1 ns) synchronization accuracy, which is critical for time-sensitive applications including robotics, telecommunications, and industrial automation.

“Designers often face major redesign challenges when adding PTP or MACsec to existing systems,” said Charlie Forni, Corporate Vice President of Microchip’s Networking and Connectivity Solutions business. “Our new transceivers simplify this process by embedding these features, allowing engineers to enhance performance, security, and scalability without compromising their existing architectures.”

The portfolio supports data rates from 1 Gbps to 25 Gbps, providing the flexibility and bandwidth needed for data centers, automation systems, and campus networks. Engineers can easily tailor their designs by selecting the appropriate media type—Optical or Direct Attach Copper (DAC)—to match application requirements.

Security is built directly into the silicon through MACsec (IEEE 802.1AE) encryption, offering hardware-level protection against common cyber threats such as eavesdropping, spoofing, denial-of-service (DoS), and man-in-the-middle attacks. This ensures the confidentiality, integrity, and authenticity of data transmitted between Ethernet devices.

Microchip’s extensive Ethernet product line spans from low-speed (10 Mbps) to high-performance (25 Gbps) solutions, including Single Pair Ethernet (SPE) devices and high port-count switches for industrial, automotive, and embedded applications. With built-in features such as enhanced security, low latency, and wide temperature tolerance, Microchip delivers reliable connectivity solutions designed for the most demanding environments.

Headquartered in Chandler, Arizona, Microchip Technology Inc is a leading provider of smart, connected, and secure embedded control solutions. Through a combination of comprehensive product portfolios, development tools, and system-level support, the company helps customers accelerate innovation across industrial, automotive, communications, consumer, aerospace, and defense markets.
