Marvell Technology Shares Rise After Annoncing Industry’s First First 802.1AE MACsec Integrated Dual 1000BT1 and 100BT1 PHY Automotive Solutions
Dec 3, 2021 By MarketDepth
Marvell Technology, Inc. (NASDAQ: MRVL) stock jumped more than 15% after the technology company announced and introduced the industry’s first 802.1AE MACsec integrated dual 1000BT1 and 100BT1 PHYs. The newly announced products extend Marvell’s leadership in automotive Ethernet PHY while aiding OEMs in the transition toward software-defined vehicles, where secure communication of data is a critical requirement. These Ethernet PHY solutions enable energy efficient, secure in-vehicle networks and assist in achieving functional safety compliance at the system level.
“The launch of 88Q2233M and 88Q120xM underscores Marvell’s commitment to developing innovative solutions for the automotive market and ushers in a new era of software-defined vehicles. Ethernet adoption is growing at a rapid pace, with future vehicle designs requiring multiple gigabit PHYs. Our new solutions seamlessly solve the issue of space constraint by integrating two 1000Base-T1 in a single package. The products also reduce the total BOM cost as many of the external components are common for the two 1000Base-T1 PHYs.”
Will Chu, senior vice president and general manager of the Automotive Business Unit, Marvell
MACsec technology secures data exchange on a hop-by-hop basis and prevents Layer 2 security threats such as intrusion, man-in-the-middle, and replay attacks. Automotive networks rely heavily on partial networking in which some segments are hibernated and woken up on demand. Marvell’s latest PHYs support 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’s new MACsec integrated dual 1000BASE-T1 and 100BASE-T1 PHYs are helping solve a critical requirement of secure communication for a new generation of software-defined vehicles. With this launch, Marvell is staking a leadership position in secure automotive Ethernet while helping tier ones and OEMs build smarter, safer and greener vehicles of the future.”
