All 1000Base-T1 test cases demonstrated for the first time
Rohde & Schwarz has teamed with chip maker Marvell to demonstrate for the first time all the 1000BASE-T1 compliance test cases for layer 1 (PHY) networking at 1Gbit/s over single twisted pair cable in automotive designs.

Using validated chipsets from Marvell and test equipment from Rohde & Schwarz, OEMs, Tier2, System Integrators and test houses can set up automotive Ethernet networks that are fully compliant with 1000BASE-T1 specifications.

All major car manufacturers are implementing Automotive Ethernet as a solution for in-vehicle communications but to provide a reliable platform for a large volume of data using the network, test and validation of the chipset design is crucial. Engineers integrating in-vehicle networks can now use the consistent, accurate and fully compliant test capabilities for automotive Ethernet, including reporting features. This enables faster development processes and gives the engineers confidence in reliable performance.

Marvell introduced the first 1000Mpbs Physical Layer transceiver optimized to meet the high bandwidth requirements of connected and autonomous vehicles. “We are excited to partner with Rohde & Schwarz to showcase the compliance of 88Q2112 to the IEEE 802.3bp standard that defines the physical layer specifications and management parameters for 1000Mbps operation over a light weight single twisted pair copper cable,” said Will Chu, Vice President and General Manager, Automotive at Marvell Semiconductor (above, right).

“We are extremely happy to be the first T&M vendor to successfully pass all 1000BASE-T1 PHY test cases together with Marvell, one of the major chipset providers. This shows that our solution based on an R&S RTO oscilloscope and an R&S ZND vector network analyzer provides consistent, accurate and trustworthy results. We continue to push the boundaries for faster Automotive Ethernet. Rohde & Schwarz looks forward to working closely with innovative partners like Marvell and their customers, providing a fully functional 1000BASE-T1 PHY compliance solution,” said Dr. Nik Dimitrakopoulos, responsible for Automotive Ethernet & Infotainment at Rohde & Schwarz.
