Dual 1000BT1 Automotive Brightlane Ethernet PHY with integrated MACsec
The Marvell® Brightlane™ 88Q2233M device has two single-pair Ethernet physical layer transceivers (PHY) that support operation over unshielded twisted pair (UTP). The transceivers implement the Ethernet physical layer portion of 1000BASE-T1 as defined by the IEEE 802.3bp standard.
The 88Q2233M 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.
88Q2233M is compliant with OPEN Alliance TC10. TC10 fast wake sleep mechanism allows implementation of partial networking and thus helps in improving vehicle energy efficiency.
The device uses advanced mixed-signal processing to perform equalization, echo and crosstalk cancellation, data recovery, and error correction at a data rate of 1 Gbps. The device achieves robust performance and exceeds electromagnetic interference (EMI) requirements in noisy environments with very low power dissipation.
