Your Vision. Our Technology
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. The device achieves robust performance and exceeds automotive electromagnetic interference (EMI) requirements in noisy environments with very low power dissipation.
