SANTA
CLARA, Calif., June 8, 2023
/PRNewswire/ -- Marvell Technology, Inc. (NASDAQ: MRVL), a
leader in data infrastructure semiconductor solutions, today
announced the Brightlane Q622x family of central Automotive
Ethernet switches, the highest capacity switches in a new, emerging
category of devices for enabling computing architectures to improve
safety and deliver software-defined services for the next
generation of vehicles.
Automotive manufacturers are rapidly shifting from architectures
built around domain networking schemes (where switches manage
devices linked to particular applications such as infotainment or
safety) and point-to-point connections to zonal networking
architectures built around more scalable Ethernet. This shift will
enable automakers to dramatically improve the onboard computing
capabilities of vehicles for advancing safety systems, enhancing
infotainment, increasing fuel efficiency and introducing
software-defined services for a better driving experience. This
shift, however, requires rethinking the technology used to build
vehicle network platforms.
Central Automotive Ethernet switches are high-bandwidth,
high-performance devices optimized to coordinate data traffic
between zonal switches, which aggregate traffic from devices
located within a physical zone of a car like processors, sensors,
actuators, storage systems and others. Typical cars based around
zonal architectures in the future will have three to up to six
zones. Using a combination of zonal and central switches will
provide automakers with a foundation for optimizing network
performance, adding new features and services and accommodating
growing bandwidth demands. Ethernet-based zonal architecture also
reduces the amount of network cabling required, which reduces
weight and manufacturing complexity.
Optimized for the most advanced automotive architectures, the
Brightlane Q6223 switch delivers 90 Gbps of bandwidth, nearly 2x
the capacity of currently available automotive switches. The
non-blocking 12-port design can be configured from among the eight
integrated 10G SerDes ports, four integrated 2.5G SerDes ports, and
two integrated 1000Base-T1 PHYs available. The Brightlane Q6222
contains nine ports for 60 Gbps, with five integrated 10G SerDes
ports, four integrated 2.5G SerDes ports, and two integrated
1000Base-T1 PHYs available for selection. Both the 90 Gbps and 60
Gbps Brightlane Q622x switches are single-chip devices to reduce
cost, power and latency.
The new switch family also includes a combination of advanced
security features not found together in any other automotive switch
product. The Brightlane Q622x family incorporates IEEE
802.1AE-2018-compliant Media Access Control (MACsec) link security
on every port, up to 10G, for encrypting data traveling between
automotive components to prevent man-in-the-middle and other
attacks. Marvell's patent-pending Ternary Content Addressable
Memory (TCAM) implementation for deep packet inspection (DPI)
provides for wirespeed packet classification to ensure packet
validity and the ability to filter and classify more than 4,000
IPv4/IPv6 flows for heightened intrusion detection. Additionally,
the Q622x family incorporates a hardware security module (HSM) for
encryption, MACsec key management and trusted boot functionality to
further secure the in-vehicle network.
"Marvell continues to deliver industry-first advances in
Automotive Ethernet technologies to meet the needs of the most
demanding customers as they develop their next-generation
software-defined vehicles," said Mike
Yeager, vice president and general manager, Automotive
Business Unit at Marvell. "With the new Brightlane switch
family, we're delivering future-proofed bandwidth, reducing BOM
space and cost, and providing the most advanced, comprehensive
combination of security features available."
Driving the Roadmap for Connected Cars
The Q622x
family is the latest addition to Marvell's comprehensive portfolio
of Automotive Ethernet switches, PHYs and camera bridges to
enable the transformation of transportation. The number of
Automotive Ethernet ports shipped annually is growing at nearly 40%
per year, with shipments expected to surpass one billion ports
annually by 2025, more than 10x the total shipped in
20181.
Marvell is collaborating with over 40 OEMs, including design
wins with eight of the 10 largest, on a variety of Automotive
Ethernet solutions.
"The software-defined car depends on new hardware. And it won't
happen without Ethernet," said Roger
Lanctot, director of Automotive Connected Mobility at
TechInsights. "By pushing the envelope on networking, Marvell is
giving automotive designers a platform for adding new services and
improving performance, while eliminating complexity. And in the
process, they'll enhance the driving experience."
