Lattice Semiconductor Corp. and Flexibilis Oy present the Flexibilis Ethernet Switch (FES) IP cores that offer triple speed (10Mbps/100Mbps/1Gbps) operation on Ethernet Layer 2 and can switch with Gigabit forwarding capacity per port.

Both Gigabit Fibre optic and Gigabit twisted pair copper Ethernet interfaces are supported. Quality of Service is supported with up to four queues per port. These Ethernet switch IP cores, available in five versions, vary in their number of ports and functionality.

The FES-HSR IP cores enable designers of smart grid substation automation and industrial networking applications to apply the emerging High-availability Seamless Redundancy (HSR) protocol using LatticeECP3 FPGAs. This IEC protocol (IEC62439-3) provides cost effective redundancy with no single point of failure and zero time to recovery in case of failure. The HSR protocol is typically used in applications where time synchronisation is also needed. Therefore IEEE 1588 Precision Timing Protocol (PTP) end-to-end transparent switch functionality is also included. The FES-HSR IP cores are applicable across a range of applications that demand high availability, gigabit-class data transfer capacity and sub-microsecond accuracy. Target applications include smart grid substation automation and networked industrial automation gear, as well as high availability network equipment.

The FES IP cores are equipped with IEEE 1588 ver2 end-to-end transparent switch functionality, which improves the ability to resist the degradation of clock information quality in larger networks. This ability is critical in meeting the strict clock quality requirements of future mobile cellular network base stations, wireline access, electrical substation and industrial automation and other control and measurement applications. Nanosecond-class accuracy in clock transfer enables backup or replacement of GPS-based synchronisation in critical applications. This feature makes the FES IP cores suitable for applications such as mobile backhaul routers, cell site routers and industrial automation products.
