The Marvell® 88Q4364 device is a single-pair Ethernet physical layer transceiver (PHY) that supports operation over shielded twisted pair (STP). The transceiver implements the Ethernet physical layer portion of 2.5G/5G/10GBASE-T1 as defined by the IEEE 802.3ch standard.
The 88Q4364 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 Graphics Processing Units (GPUs), CPUs, Ethernet switches, and Electronic Control Units (ECUs) via 10G/5G/2.5G USXGMII, 10 Gbps XFI, 5 Gbps XFI/2, 2.5 Gbps 2500BASE-X, or 2.5 Gbps OCSGMII interface to support the operations and network rates required for In-Vehicle Networks (IVN).
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。
