Renesas introduces single-channel Ethernet physical layer devices

Customers are provided with compatibility with standard Ethernet communication protocols, says the company

By CBR Staff Writer

Semiconductor offerings provider Renesas Electronics has released two single-channel Ethernet physical layer (PHY) devices for industrial communication systems with part numbers µPD60610GA-GAM-AX and µPD60611GA-GAM-AX.

The two new PHY chips expand Renesas’ family of PHY devices designed for industrial Ethernet requirements, which includes two dual-channel PHY devices.

The new PHY devices µPD60610 and µPD60611 PHY deliver high-speed, real-time data transmission and error-free reception due to their low node latency and low jitter.

Renesas’ new PHY devices provide high-speed link-up and link-down control, fast link-loss recognition needed by real-time protocols like PROFINET, SERCOSIII and EtherCAT.

In addition, the µPD60611 single-channel PHY device enables one-step and two-step mode operations and a number of time-trigger outputs to external applications that need synchronous time information by supporting the Precision Time Protocol (PTP) based on the IEEE 1588-V2 standard.

The new PHY device also provides accuracy levels needed for time synchronisation, a feature required by several types of applications including motion control, AvB (audio video bridging), and sequences of events, one nanosecond-accurate (1 ns-accurate) and precise timestamp for incoming and outgoing telegrams and supports cable-quality monitoring to facilitate maintenance and repair work.

Renesas’ PHY technology benefits industrial customers by providing compatibility with standard Ethernet communication protocols and the new devices compliant with the IEEE 802.3 standard and are suitable for implementation in demanding industrial environments.
