May 4, 2018 (Beijing) Texas Instruments (NASDAQ: TXN) recently introduced a new automotive Ethernet physical layer (PHY) transceiver that reduces the number of external components and board space Half, and at the same time, power consumption is only half that of the same type of solution. The DP83TC811S-Q1 supports SGMII, small package and integrated diagnostics, enabling designers to connect space-constrained automotive body electronics, infotainment systems and clusters via Ethernet and Advanced ADAS applications. For more information, please visit the link.
As the first 100BASE-T1 device to support SGMII, the DP83TC811S-Q1 Ethernet PHY enhances design flexibility by connecting multiple switches and interfaces. The DP83TC811S-Q1 supports a full range of MIIs, enabling designers to use a variety of MACs and processors ( Such as TI's JacintoTM automotive processor) for Ethernet connectivity. To help the system monitor and detect cable breaks, temperature and voltage changes, and electrostatic discharge (ESD) conditions, the DP83TC811S-Q1 is equipped with a patent-pending ESD monitor. Diagnostic Toolkit.
Key Features and Benefits of the DP83TC811S-Q1 Ethernet PHY • Smaller size and lighter weight: In addition to requiring fewer external components, the DP83TC811S-Q1 is also available in a 6mm x 6mm wet side package, allowing solution size 50% smaller. In addition, the device complies with IEEE 802.3bw standard and OPEN Alliance certification. Unshielded single twisted pair copper cable can be used to reduce total cable weight and cost. • Lowest power consumption: The DP83TC811S-Q1 is developed using one of TI's low-power process technologies. It consumes low power, minimizes heat dissipation, and allows smaller gaps between components. The device also features power-saving features such as standby, disable, and wake-up LAN (LAN). • Powerful and intelligent design: The integrated diagnostics toolkit provides cable diagnostics, temperature and voltage sensors, and ESD monitors, enabling engineers to create application designs that withstand ESD and voltage events. These diagnostic features enable designers to continue Monitors the integrity of the Ethernet link. In addition, the DP83TC811S-Q1 provides up to 8kV of ESD protection to help shield equipment against high-voltage faults. • Simplified layout Flexible, excellent performance: SGMII uses only 4 pins instead of the 12 required pins for RGMII, which reduces the board size and number of traces, which simplifies the design layout. In addition, physical medium correlation (PMD) filtering The integration of the MII series terminators, PMD terminals and power filter components reduces the need for external discrete circuits, adding more board space for designers to add more functionality. The DP83TC811S-Q1 has as low as 140 ns. Delay, which enables key systems such as automotive ADAS to respond and communicate more quickly.
Tools and Support Designers can use the DP83TC811SEVM evaluation module to easily evaluate the device and its SGMII technical support. If the designer only needs RGMII, the DP83TC811EVM evaluation module can be used. Both products receive a value of $299 through TI shops and authorized distributors. Benefits. Engineers can also start their system design with a car independent gateway reference design and a cost-effective in-vehicle infotainment system reference design.
Packaging, Availability, and Pricing The DP83TC811S-Q1 is available now in a very thin 36-pin wet side quad flat no-lead package (VQFNP). Available through Texas Instruments stores and authorized distributors, the price is $2.25 per thousand.
