SANTA
CLARA, Calif., Dec. 2, 2021
/PRNewswire/ -- Marvell (NASDAQ: MRVL) today 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.
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 dual 1000BT1 88Q2233M with MACsec and 100BT1
88Q120xM with MACsec are the latest additions to the Brightlane PHY
automotive portfolio. With the introduction of these groundbreaking
solutions, Marvell achieves several industry firsts, including the
first to launch an 802.3bp compliant dual 1000BT1 PHY with MACsec
integrated, and the first to launch an 802.3bw compliant 100BT1 PHY
with MACsec integrated.
"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," said
Will Chu, senior vice president and
general manager of the Automotive Business Unit, Marvell. "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."
"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,"
said Ian Riches, vice president for
the Global Automotive Practice, Strategy Analytics. "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."
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 Open Alliance TC1 and
TC12. As Marvell's third-generation automotive ethernet PHYs,
88Q2233M and 88Q120xM are built on proven automotive architectures
that deliver best-in-class EMI/EMC performance.
Key Features:
- 88Q2233M: Dual 1000BASE-T1, IEEE 802.3bp-compliant
Ethernet PHY supports operation over unshielded twisted pair
(UTP)
- 88Q120xM: 100BASE-T1, IEEE 802.3bw-compliant Ethernet
PHY supports operation over unshielded twisted pair (UTP)
- Supports IEEE 802.1AE MACsec: Support MACsec that
provides layer 2 security and prevents security threats such as
intrusion, man-in-the-middle, and replay attacks
- Supports OPEN Alliance TC10 Sleep Mode: Support TC10
fast wake-sleep mechanism to enable partial networking
- 802.1AS, 802.1AS-Rev PTP: Support precision timing
protocol that enables extremely precise time synchronization of
networks
- Integrated Voltage Regulators: Support single 3.3V
supply mode and saves overall BOM cost
- ASPICE Level 2 software: Enables faster time-to-market
with reuse of a flexible API and robust solution
Availability:
The Marvell 88Q2233M and 88Q120xM are currently sampling along
with their development boards.
