Ethernet PHY ASSP
NEC Electronics' Industrial Ethernet PHY family exhibits very competitive round trip delay for a discrete Ethernet PHY device. Therefore developers experience lowest node latency and system jitter, two features that are required for reliable high performance real time Ethernet systems. As Ethernet based technologies becomes more and more popular in Industrial Automation traditional discrete Ethernet PHY products will not enable the differentiation demanded by application developers. NEC Electronics Ethernet PHY family shows our expertise in cutting edge technology and architecture.
Features
Designed for Industrial
Industrial Ethernet places new demands on technology and NEC's Ethernet PHY family delivers on these. Increasingly the ability to quickly swap out tools and machines is becoming more and more important and this requires enhanced handling of link-up and link-down procedures. Monitoring cable quality for maintenance cycles is crucial for maintaining high system reliability and availability. NEC's Ethernet PHY family implements line quality monitoring features, which makes it easier to monitor the quality of the line. To properly implement most real time industrial Ethernet protocols Precision Time Protocol (PTP) must be implemented. In order to do this an IEEE1588 PTP timer is necessary, which is included on the enhanced variants of NEC's Industrial Ethernet PHY. These key features differentiate our industrial Ethernet PHY family and provide developers of Industrial Ethernet applications unique qualities not available in existing implementations.
Basic Features
- 1ch/2ch PHY (Physical interface)
- IEEE802.3 compliant
- 10BaseT/100BaseTX/100BaseFX port
- Auto negotiation
- Auto Polarity detection
- MDI/MDI-X Auto-Cross Over
- MII/RMII port
- Single power supply (3.3V)
Supporting Legacy and Integration
An important feature of the Ethernet PHY family is that it is completely backwards compatible with standard Ethernet communications allowing the integration of enterprise and industrial environment to occur more smoothly. The family compliant with the IEEE802.3 standard and is UNH tested. It has also been quality tested for robust environment making possible even to bring enterprise applications to the plant floor. NEC's industrial PHY family supports the absolute integration within a plant and prepares systems to future needs. Furthermore the Ethernet PHY family is complimentary to our other Ethernet based products like V850 microcontrollers and ERTEC industrial Ethernet controllers. Developers can find a complete solution portfolio to support legacy and aid the integration of Ethernet in industrial automation.
