Renesas Electronics Corporation Expands Lineup of Ethernet PHY Chips with Two Single-Channel Industrial Ethernet PHY Chips
Renesas Electronics has announced the availability of two single-channel Ethernet physical layer (PHY, part number µPD60610GA-GAM-AX and µPD60611GA-GAM-AX) devices for industrial communication systems. The two new PHY chips expand Renesas’ family of PHY devices designed for industrial Ethernet requirements, which includes two dual-channel PHY devices (the µPD60620GA-GAM-AX and the µPD60621GA-GAX-AX).Rece
Key features of the µPD60610 and µPD60611 PHY devices:
(1) Specific focus on lowest system latency and jitter
The new PHY devices deliver high-speed real-time data transmission and error-free reception due to their low node latency and low jitter.
(2) Enhanced link control
The new single-channel PHY devices provide high-speed link-up and link-down control which is ideally suited to robotics and similar applications.
(3) Enhanced diagnostics features for permanent cable quality monitoring
Renesas Electronics’ new PHY devices provide the fast link-loss recognition needed by real-time protocols like PROFINET, SERCOSIII and EtherCAT. They also support cable quality monitoring to facilitate maintenance and repair work.
(4) Support of IEEE1588 V2 standard
The µPD60611 single-channel PHY device supports the precision time protocol (PTP) 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 new PHY 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 (nanosecond) accurate and precise timestamp for incoming and outgoing telegrams.
Renesas’ PHY technology benefits industrial customers who use Ethernet networks by offering unique features that have not been available in the market until now. Along with providing compatibility with standard Ethernet communication protocols such as Ethernet/IP, SERCOSIII, PROFINET or EtherCAT, the new PHY devices are also compliant with the IEEE802.3 standard and are suitable for implementation in demanding industrial environments. The new PHY chips expand Renesas’ range of product lineups for Ethernet-based industrial networks, which include Ethernet microcontrollers (MCUs) and PROFINET ASSPs, such as ERTEC and TPS-1. Renesas’ PHY technology is also available as intellectual property (IP) products for customised designs.
