Texas Instruments (TI) introduced a new automotive Ethernet physical layer (PHY) transceiver that cuts the external component count and board space in half and consumes as little as half the power of competitive solutions.
The DP83TC811S-Q1's support for serial gigabit media independent interface (SGMII), small packaging and integrated diagnostic features enable designers to bring greater intelligence via Ethernet connectivity to space-constrained automotive body electronics, infotainment and cluster, and advanced driver assistance systems (ADAS) applications.
As the first 100BASE-T1 device to support SGMII, the DP83TC811S-Q1 Ethernet PHY improves design flexibility by enabling connections to multiple switches and interfaces. The DP83TC811S-Q1 supports the full range of media independent interfaces (MII), which enables designers to implement Ethernet connectivity with various media access controllers (MACs) and processors such as TI's Jacinto automotive processors.
To help the system monitor and detect cable breaks, temperature and voltage variations, and electrostatic discharge (ESD) events, the DP83TC811S-Q1 features a diagnostic toolkit, including a patent-pending ESD monitor.
