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

Market leader of in-motor vehicle network engineering introduces 3rd technology of secure automotive gigabit Ethernet PHY

SANTA CLARA, Calif., Oct. 7, 2020 /PRNewswire/ — Marvell (NASDAQ: MRVL) nowadays released the industry’s very first automotive gigabit Ethernet PHY option with built-in media obtain command security (MACsec) technologies for secure place to point interaction. With virtually a billion linked vehicles projected to be on the highway by 2030, the integration of protection will become an vital issue in tomorrow’s autos. MACsec engineering fortifies in-vehicle networking by securing information exchange on a hop-by-hop foundation and prevents Layer 2 stability threats such as intrusion, guy-in-the-middle, and replay assaults. Marvell’s new Open Alliance TC10 compliant, dual speed 100/1000 Base-T1 88Q222xM Ethernet PHY permits energy productive, secure in-car networks and assists in achieving functional basic safety compliance at the system level.

Automotive networks count seriously on partial networking in which some segments are hibernated and woken up on desire. Marvell’s new gigabit PHY supports the Open Alliance TC10 for sleep method and wake-up, tailored for automotive use circumstances. TC10 manage signals are despatched over the knowledge line and lower the require for exclusive cables for remote management of the PHY states. Fast electrification of vehicles has resulted in lessened electric power funds for each individual component. As the industry’s lowest energy gigabit Ethernet PHY and with aid of TC10, Marvell’s 88Q222xM aids tier1s and OEMs to style and design vitality economical in-automobile community architectures.

Marvell is dedicated to creating modern methods for the automotive sector and presents the industry’s premier portfolio of protected Ethernet switches and PHYs,” mentioned Amir Bar-Niv, vice president of Marketing and advertising of the Automotive Company Device at Marvell. “We are really very pleased to introduce the industry’s 1st automotive gigabit Ethernet PHY that integrates Layer 2 protection by way of MACsec whilst also delivering greatest-in-class decrease electricity general performance that satisfies the most stringent electricity spending budget. Marvell’s 88Q222x resolution is primarily based on the Automotive QMS Course of action and will come with practical security collateral assisting tier-1s and OEMs in satisfying ISO 26262 at a technique amount.”

“With at any time increasing details and intelligence in the related vehicles, the want for extensive cyber stability methods is crucial,” mentioned Dr. Lars Völker, specialized fellow at Technica Engineering. “MACsec IEEE 802.1AE efficiently implements a layer of stability for escalating bandwidth demands, while preserving the system deterministic and the complexity at a minimal permitting OEMs to construct quickly setting up techniques with no the dependencies of the interaction stack. Marvell’s 88Q222xM Ethernet PHY solution spouse and children with MACsec security lets us to establish primary analysis platforms and test instruments for automotive OEMs who are analyzing MACsec on various speed grades.”

“The speedy evolution of purchaser gadgets is driving a lot more and additional options into present day cars and trucks, at an at any time-growing pace, resulting in a want for greater community bandwidth, lessen latency and greater connectivity amongst auto ECUs. The present blend of auto networks basically are unable to scale to these prerequisites and therefore we are looking at a megatrend towards homogenous Ethernet-based in-automobile networks,” claimed Ian Riches, vice president of Automotive Follow, & Director Technique Analytics Ltd. “These will also enable apply the power effectiveness and cyber security functions that will be wanted. It is as a result enjoyable to see the integration of Open Alliance TC10 and MACsec in Marvell’s new 3rd-technology PHY, as it supplies a path to pace the implementation of tomorrow’s in-car or truck networks.”

As automotive networks are required to function in noisy environments, products need to be equipped to do the job together without having interference. All elements on the community ought to meet the electromagnetic interference/electromagnetic compatibility (EMI/EMC) prerequisites in accordance with the Open up Alliance TC12. As Marvell’s third-era gigabit PHY, 88Q222xM is built on verified automotive architectures that supply greatest-in-course EMI/EMC efficiency.

88Q222xM Important Features:

  • 1000Foundation-T1, IEEE 802.3bp-compliant 100Base-T1, IEEE 802.3bw-compliant: Pin compatible twin pace Ethernet PHY supports procedure above unshielded twisted pair (UTP)
  • Supports IEEE 802.1AE MACsec: MACsec supplies layer 2 safety and helps prevent security threats such as intrusion, male-in-the-middle, and replay attacks
  • Supports Open Alliance TC10 Snooze Method: 88Q222xM supports TC10 speedy wake-slumber system to empower partial networking
  • AEC Q100 Grade 1 Certified: 88Q222xM is certified to be used in severe automotive ecosystem with ambient temperature ranging from -40℃ to 125℃
  • 802.1AS, 802.1AS-Rev PTP: 88Q222xM Supports precision timing protocol that enables very exact time synchronization of networks
  • Package deal: 88Q222xM arrives in a modest 40pin QFN, 6.0×6. mm, .5 mm pitch bundle with wettable flanks
  • Built-in Voltage Regulators: Supports one 3.3V source method and saves general BOM price
  • ASPICE Stage 2 software: Enables faster time-to-current market with reuse of a adaptable API and strong answer

Marvell 88Q2220M, 88Q2221M are presently sampling along with their enhancement boards.
