Marvell  claims to have introduced the industry’s first automotive gigabit Ethernet PHY solution with integrated media access control security (MACsec) technology for secure point to point communication.

MACsec technology fortifies in-vehicle networking by securing data exchange on a hop-by-hop basis and prevents Layer 2 security threats such as intrusion, man-in-the-middle, and replay attacks.

Marvell’s Open Alliance TC10 compliant, dual speed 100/1000 BASE-T1 88Q222xM Ethernet PHY enables energy efficient, secure in-vehicle networks and assists in achieving functional safety compliance at the system level.

Automotive networks rely on partial networking in which some segments are hibernated and woken up on demand.

Marvell’s gigabit PHY supports the Open Alliance TC10 for sleep mode and wake-up, tailored for automotive use cases.

TC10 control signals are sent over the data line and minimize the need for special cables for remote control of the PHY states.

Rapid electrification of vehicles has resulted in reduced power budget for each component.

Marvell claims it as the industry’s lowest power gigabit Ethernet PHY which, with support of TC10, Marvell’s 88Q222xM, aids Tier1s and OEMs to design energy efficient in-vehicle network architectures.
