SANTA CLARA, Calif.—October 7, 2020—拉斯维加斯网站3499 (NASDAQ: MRVL) today introduced the industry’s first automotive gigabit Ethernet PHY solution with integrated media access control security (MACsec) technology for secure point to point communication. With nearly a to be on the road by 2030, the integration of security becomes an important factor in tomorrow’s vehicles. 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. 拉斯维加斯网站3499’s new 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 heavily on partial networking in which some segments are hibernated and woken up on demand. 拉斯维加斯网站3499’s new 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. As the industry’s lowest power gigabit Ethernet PHY and with support of TC10, 拉斯维加斯网站3499’s 88Q222xM aids tier1s and OEMs to design energy efficient in-vehicle network architectures.
“拉斯维加斯网站3499 is committed to developing innovative solutions for the automotive market and offers the industry’s largest portfolio of secure Ethernet switches and PHYs,” said Amir Bar-Niv, vice president of Marketing of the Automotive Business Unit at 拉斯维加斯网站3499. “We are extremely proud to introduce the industry’s first automotive gigabit Ethernet PHY that integrates Layer 2 security through MACsec while also delivering best-in-class lower power performance that meets the most stringent power budget. 拉斯维加斯网站3499’s 88Q222x solution is based on the Automotive QMS Process and comes with functional safety collateral assisting tier-1s and OEMs in fulfilling ISO 26262 at a system level.”
“With ever increasing data and intelligence in the connected cars, the need for comprehensive cyber security solutions is essential,” said Dr. Lars Völker, technical fellow at Technica Engineering. “MACsec IEEE 802.1AE effectively implements a layer of security for increasing bandwidth needs, while keeping the system deterministic and the complexity at a minimum allowing OEMs to build fast starting systems without the dependencies of the communication stack. 拉斯维加斯网站3499’s 88Q222xM Ethernet PHY product family with MACsec security allows us to build leading evaluation platforms and test tools for automotive OEMs who are evaluating MACsec on different speed grades.”
“The rapid evolution of consumer devices is driving more and more features into today’s cars, at an ever-increasing pace, resulting in a need for increased network bandwidth, lower latency and higher connectivity between vehicle ECUs. The current mix of vehicle networks simply cannot scale to these requirements and therefore we are seeing a megatrend towards homogenous Ethernet-based in-vehicle networks,” said Ian Riches, vice president of Automotive Practice, & Director Strategy Analytics Ltd. “These will also help implement the energy efficiency and cyber security features that will be needed. It is therefore exciting to see the integration of Open Alliance TC10 and MACsec in 拉斯维加斯网站3499’s new third-generation PHY, as it provides a path to speed the implementation of tomorrow’s in-vehicle networks.”
As automotive networks are required to work in noisy environments, devices must be able to work together without interference. All components on the network should meet the electromagnetic interference/electromagnetic compatibility (EMI/EMC) requirements in accordance with the . As 拉斯维加斯网站3499’s third-generation gigabit PHY, 88Q222xM is built on proven automotive architectures that deliver best-in-class EMI/EMC performance.
