A new automotive Ethernet physical layer (PHY) transceiver has been introduced by Texas Instruments. It 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.
Key features and benefits of the DP83TC811S-Q1 Ethernet PHY
Tools and support to speed design
Designers can easily evaluate the device and its SGMII support with the DP83TC811SEVM evaluation module. Designers who need only RGMII can use the DP83TC811EVM evaluation module. Engineers can also jump-start their system design with the Automotive Stand-Alone Gateway Reference Design and the Cost-Effective In-Vehicle Infotainment System Reference Design.
