New Family of Industrial 10/100 Ethernet PHY with IEEE1588
The new PHYs offer the best-in-class industrial connectivity with lowest latency and advanced cable diagnostics, and are optimized for existing industrial Ethernet protocols used in industrial automation products.
Electronics introduces a new family of industrial Ethernet physical layers (PHYs) for 10Base-T and 100Base-TX/FX.
Key features
- Industry-leading high-speed data transfer
The new PHYs enable lowest node latency, delivering high-speed data transmission and reception without failure. - Enhanced link control
With a powerful link control, NEC Electronics’ new PHYs provide high-speed link-up and link-down control mechanism. - Advanced cable monitoring and diagnostic features
The new PHYs enable consistent cable quality monitoring for easy maintenance, and support easy repair during the maintenance cycle. Failures can be detected before they happen, which improves automation system reliability. The cable diagnostic feature is based on the time domain reflectometer (TDR) function that determines and localizes cable problems. - Accurate time stamping, IEEE1588
With the IEEE1588 time stamping of transmitted and received packets, the new PHYs provide outstanding timing precision by enabling continuous and automatic process where the clock differences are noted and automatically adjusted. The time stamping of transmitted and received packets allows designers to determine the difference between clock frequencies and correct for them achieving real-time performance. The PHYs fully support IEEE1588 PTP V2. - General Features
Fully compliant with IEEE 802.3 / 802.3u for 100Base-TX, 100Base-FX and 10Base-T, Auto-negotiation and parallel detection, Full and half duplex operation, MDI/MDI-X crossover, Single 3.3V power supply.
Four products will be available, a Dual-PHY with or without IEEE1588 and a Single-PHY with or without IEEE1588.
NEC Electronics’ family of PHYs provides users of Ethernet communication in industrial environments with unique features that are not available in existing implementations. The new PHYs are compatible with standard industrial Ethernet communication protocols such as
- EtherCAT
- EtherNet/IP
- SERCOS III
- Ethernet Powerlink
- Profinet
They are also compliant with IEEE802.3 and qualify for robust industrial environments. NEC Electronics’ new PHYs enhance the company’s other Ethernet-based product offerings such as V850 Ethernet-based microcontrollers (MCUs), ASSPs and ASICs and are also available as embeddable macros for these products.
