The Marvell® Brightlane™ QB5224 device is an automotive Ethernet Bridge device that bridges 4 lanes of MIPI CSI-2 with an automotive ethernet PHY. 88QB5224 supports operation over shielded twisted pair (STP) and implements the Ethernet physical layer portion of 10GBASE-T1 as defined by the IEEE 802.3ch standard.
The 88QB5224 has integrated MACsec that secures against the Layer 2 In-Vehicle Networking security threats. MACsec secures data exchange on a hop-by-hop basis and prevents attacks such as intrusion, man-in-the-middle, and replay attacks.
The device is designed to directly connect to automotive-grade cameras, Graphics Processing Units (GPUs) and more, via CSI-2 interface as defined by the MIPI Alliance.
The device uses advanced mixed-signal processing to perform equalization, echo cancellation, data recovery, and error correction at full line rate. 安定したパフォーマンスを実現し、消費電力をたいへん低く抑え、ノイズ環境下での自動車の電磁妨害 （EMI） 要件を満たすことができます。
