Renesas ethernet PHY chip range

Renesas has available two single-channel ethernet physical layer devices for industrial communications systems.

The chips expand the company’s family of PHY devices designed for industrial ethernet requirements, which includes two dual-channel PHY devices.

Key features of the devices include: specific focus on lowest system latency and jitter. They deliver high-speed real-time data transmission and error-free reception due to their low node latency and low jitter; enhanced link control; enhanced diagnostics features for permanent cable quality monitoring. These provide fast link-loss recognition needed by real-time protocols such as Profinet, SERCOSIII and EtherCAT. They also support cable quality monitoring to facilitate maintenance and repair; support for IEEE1588 V2 standard.

The µPD60611 single-channel device supports the precision time protocol based on the IEEE1588-V2 standard. This enables one-step and two-step mode operations and a number of time trigger outputs to external applications that need synchronous time information.

The device also provides the highest accuracy levels needed for time synchronisation. This feature is required by several types of application, including motion control, AvB (audio video bridging) and sequences of events. The device also provides a 1 ns accurate and precise timestamp for incoming and outgoing telegrams.
