NEC's new 10Base-T and 100Base-TX/FX Ethernet physical layer chips

NEC Electronics has announced the development of new family of 10Base-T and 100Base-TX/FX Ethernet physical layer (PHY) devices that offers high-speed industrial connectivity and advanced cable diagnostics for industrial automation systems.

The key features of the new Ethernet physical layers are,

High-speed data transfer
Enable low node latency, delivering high-speed data transmission and reception without failure.
Enhanced link control, and provides high-speed link-up and link-down control mechanism
Accurate time stamping

The new PHYs are compatible with industrial Ethernet communication protocols such as EtherNet/IP, SERCOS III, EtherCAT or Profinet. They are also compliant with IEEE802.3 and qualify for robust industrial environments. NEC Electronics' new PHYs enhance 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.

"Our new PHY family demonstrates NEC Electronics' commitment to the industrial automation markets and underlines our leading position in communication networks today," said Kazuyoshi Yamada, vice president, 1st SoC Operations Unit, NEC Electronics Corporation. "Our PHY technology provides robust, high-performance Ethernet-based network solutions to deliver multiple innovations for the industry's automation systems."

Availability: Mass production expected to start in Q3 of 2010
