Ethernet camera bridge for in-vehicle video distribution

New Products |
By Rich Pell


The latest addition to the company’s Brightlane automotive portfolio, the 88QB5224 multi-gig Ethernet camera bridge provides standardization for in-vehicle video distribution in multiple areas including IEEE 802.3ch compliant 10GBASE-T1 PHY, IEEE 802.1AE MACsec for security, time synchronization, energy efficient Ethernet for power savings, power over data line, and time sensitive network. The Ethernet-based camera bridge enables development of interoperable software that delivers key services through a multilayer communication stack.

It also provides a mature ecosystem of service delivery through software-based architecture. The company says that it is the first to launch a 10G Ethernet camera bridge for distributing uncompressed video, and the first to aggregate four cameras through a single device.

“We are extending our leadership in Ethernet-based solutions to enable autonomous driving and usher in the next generation of automotive architectures,” says Will Chu, senior vice president and general manager of the Automotive Business Unit, Marvell. “Marvell’s newest Ethernet bridge solution builds on the introduction of our multi-gig 802.3ch Ethernet 10Gbps PHY, integrated with image sensor interface. The new Ethernet device underscores Marvell’s commitment to enabling smarter, safer and greener vehicles with innovative automotive networking, storage, compute and security semiconductor solutions.”

Key features of the 88QB5224 include:

  • 4 lanes of MIPI CSI-2 Rx/Tx
  • 10GBASE-T1, IEEE 802.3ch compliant PHY
  • Supports IEEE 802.1AE MACsec
  • I2C Support
  • AEC-Q100 Grade 2 (-40°C to +105°C)
