Marvell Unveils Industry’s 1st Automotive Gigabit Ethernet PHY with MACsec Safety

SANTA CLARA, Calif., Oct. 7, 2020 /PRNewswire/ — Marvell (NASDAQ: MRVL) today introduced the industry’s first automotive gigabit Ethernet PHY solution with integrated media obtain manage protection (MACsec) technological innovation for secure level to place conversation. With approximately a billion linked vehicles projected to be on the road by 2030, the integration of safety gets to be an critical variable in tomorrow’s autos. MACsec engineering fortifies in-motor vehicle networking by securing details trade on a hop-by-hop foundation and helps prevent Layer 2 security threats such as intrusion, man-in-the-middle, and replay attacks. Marvell’s new Open up Alliance TC10 compliant, dual pace 100/1000 Foundation-T1 88Q222xM Ethernet PHY allows electricity productive, secure in-car networks and helps in accomplishing useful basic safety compliance at the program degree.

Automotive networks depend closely on partial networking in which some segments are hibernated and woken up on need. Marvell’s new gigabit PHY supports the Open Alliance TC10 for slumber mode and wake-up, personalized for automotive use situations. TC10 control alerts are despatched about the knowledge line and lower the will need for distinctive cables for remote command of the PHY states. Rapid electrification of autos has resulted in lessened electrical power spending plan for every single element. As the industry’s lowest ability gigabit Ethernet PHY and with support of TC10, Marvell’s 88Q222xM aids tier1s and OEMs to style strength efficient in-auto network architectures.

“Marvell is dedicated to producing ground breaking answers for the automotive current market and features the industry’s premier portfolio of protected Ethernet switches and PHYs,” claimed Amir Bar-Niv, vice president of Advertising and marketing of the Automotive Enterprise Device at Marvell. “We are really happy to introduce the industry’s first automotive gigabit Ethernet PHY that integrates Layer 2 safety through MACsec while also delivering very best-in-course lower electric power general performance that meets the most stringent power funds. Marvell’s 88Q222x answer is centered on the Automotive QMS System and will come with functional security collateral assisting tier-1s and OEMs in fulfilling ISO 26262 at a technique degree.”

“With at any time growing facts and intelligence in the linked automobiles, the need for comprehensive cyber safety methods is essential,” said Dr. Lars Völker, technical fellow at Technica Engineering. “MACsec IEEE 802.1AE properly implements a layer of protection for escalating bandwidth requirements, when preserving the system deterministic and the complexity at a minimum letting OEMs to establish rapid commencing units without having the dependencies of the interaction stack. Marvell’s 88Q222xM Ethernet PHY product or service family with MACsec safety enables us to construct foremost analysis platforms and test tools for automotive OEMs who are assessing MACsec on various pace grades.”

“The immediate evolution of buyer devices is driving more and extra functions into present day vehicles, at an ever-growing tempo, ensuing in a have to have for increased community bandwidth, decreased latency and greater connectivity among motor vehicle ECUs. The existing blend of vehicle networks simply can’t scale to these necessities and for that reason we are viewing a megatrend in the direction of homogenous Ethernet-dependent in-car networks,” stated Ian Riches, vice president of Automotive Exercise, & Director Approach Analytics Ltd. “These will also aid put into practice the power performance and cyber stability attributes that will be wanted. It is hence interesting to see the integration of Open up Alliance TC10 and MACsec in Marvell’s new 3rd-generation PHY, as it offers a path to velocity the implementation of tomorrow’s in-vehicle networks.”&#13

As automotive networks are needed to work in noisy environments, gadgets ought to be able to operate together with out interference. All parts on the community should fulfill the electromagnetic interference/electromagnetic compatibility (EMI/EMC) demands in accordance with the Open up Alliance TC12. As Marvell’s 3rd-era gigabit PHY, 88Q222xM is designed on proven automotive architectures that supply most effective-in-course EMI/EMC functionality.

88Q222xM Crucial Capabilities:

  • 1000Base-T1, IEEE 802.3bp-compliant 100Foundation-T1, IEEE 802.3bw-compliant: Pin compatible dual pace Ethernet PHY supports operation more than unshielded twisted pair (UTP)
  • Supports IEEE 802.1AE MACsec: MACsec delivers layer 2 protection and prevents stability threats this kind of as intrusion, male-in-the-middle, and replay assaults
  • Supports Open Alliance TC10 Snooze Mode: 88Q222xM supports TC10 rapid wake-snooze mechanism to enable partial networking
  • AEC Q100 Grade 1 Experienced: 88Q222xM is experienced to be employed in harsh automotive surroundings with ambient temperature ranging from -40℃ to 125℃
  • 802.1AS, 802.1AS-Rev PTP: 88Q222xM Supports precision timing protocol that enables really exact time synchronization of networks
  • Deal: 88Q222xM comes in a compact 40pin QFN, 6.0×6. mm, .5 mm pitch package deal with wettable flanks
  • Built-in Voltage Regulators: Supports single 3.3V offer method and saves all round BOM value
  • ASPICE Degree 2 application: Enables a lot quicker time-to-industry with reuse of a adaptable API and sturdy remedy
