Marvell’s second generation 100BASE-T1 exceeds automotive electromagnetic interference requirements with low-power dissipation and previous generation pin compatibility
Marvell announced the launch of its second generation 88Q1110/88Q1111 100BASE-T1 automotive Ethernet PHY with the lowest power consumption in the industry. Connected cars require many more in-vehicle, high-speed data applications than ever before, prompting the need for innovative automotive solutions to effectively move data around the car. As a leader in networking solutions, Marvell provides a complete portfolio of automotive qualified switches, PHYs, and controller solutions that are implemented into various in-vehicle domains such as infotainment, gateway, and ADAS. The launch of Marvell’s second generation 100BASE-T1 PHY broadens the physical layer transceiver product line which spans from 100Mbps to multi-gigabit and enables reliable and standards-based platforms optimized to address data-intensive applications.

In addition to low-power capability, the second generation PHY also leverages existing designs, ensuring backwards pin compatibly to previous solutions already in production; as well as supports the OPEN Alliance TC10 Sleep Mode – enabling a universal wake-up and sleep signal to save power when not in use.
Bar-Niv continued: “As the connected car trend continues to gather pace and more technologies are designed into vehicles, the 100BASE-T1 PHYs will become increasingly crucial in Ethernet-based vehicle networks to securely connect the multiple endpoints required to transfer all of the data, while also protecting vehicles from malicious attacks or compromises to the data streamed in the vehicle.”
