The Marvell® 88Q222xM device is a single-pair Ethernet physical layer transceiver (PHY) that supports operation over unshielded twisted pair (UTP). The transceiver implements the Ethernet physical layer portion of 1000BASE-T1 as defined by the IEEE 802.3bp standard.
The 88Q222xM 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.
88Q222xM is compliant to 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 either 1 Gbps. The device achieves robust performance and exceeds electromagnetic interference (EMI) requirements in noisy environments with very low power dissipation.
