Simplify space-constrained automotive application designs with robust 100BASE-T1 Ethernet PHY

Texas Instruments has a new automotive Ethernet PHY transceiver that reduces the external component count and board space by half and uses as little as half the power of competitive solutions. The DP83TC811S-Q1’s support for SGMII, small packaging and integrated diagnostic features allow designers to bring higher intelligence via Ethernet connectivity to space-constrained automotive body electronics, infotainment and cluster, and ADAS applications. As the first 100BASE-T1 device to support SGMII, the device increases design flexibility by allowing connections to multiple switches and interfaces. The device supports the full range of MII, which allows designers to implement Ethernet connectivity with various MACs and processors such as the company’s Jacinto automotive processors. To help the system monitor and detect cable breaks, temperature and voltage fluctuations, and ESD events, the device features a diagnostic toolkit, including a patent-pending ESD monitor.
