Overview

The 800Gbps Ethernet IP solution offers a fully integrated Ethernet Technology Consortium (ETC) compliant solution for use in core networks, Ethernet switching and network interface card (NIC) applications. The Ethernet cores implement an efficient architecture to achieve best in class resource utilization and performance numbers for targeting the complete 800Gbps Ethernet solution to ASICs as well as FPGAs. The ETC 800G Ethernet is designed as an interface that uses eight 106Gb/s lanes using two IEEE802.3 400G PCS instances with a single IEEE802.3 compliant 800G MAC.

Enhancing Ethernet Security with MACsec

Ethernet was originally designed for high-speed data transfer and interoperability between devices. However, traditional Ethernet does not provide built-in mechanisms for securing data traffic, such as encryption or authenticity protection. This is where MACsec comes into the picture.

What Makes Ethernet IP Truly Automotive-Grade

This blog examines what separates truly automotive-grade Ethernet IP from generic implementations across functional safety, time-sensitive networking, security, observability, lifecycle management, and the integration disciplines that only become visible once a program is deep into development.
