MACsec Engine, 1G to 50G Single-Port, with TSN support

Overview

The MACsec-IP-161 is a versatile MACsec solution for silicon devices that require plug-and-play MACsec processing for an Ethernet port at full line rate. It provides classification, transformation and statistics for the IEEE802.1AE standard MACsec.

Additionally, it supports VLAN-in-clear use cases, IEEE802.3br preemption and Cisco ClearTags protocols. The IP-161 is available in numerous configurations optimized for desired throughput range, number of secure connections and features set. Supplied with software support, the MACsec-161 is the ideal solution for TSN Ethernet PHYs, switches, automotive, 5G SoCs and many other Ethernet-connected applications.
