NXP adds to its RoadLINK ICs, targeting ‘car-to-X’ communications

June 12, 2014 // By Graham Prophet
TEF510x is the second product in NXP’s RoadLINK range; it is a dual radio multi band RF transceiver for Car-to-X (C2X) applications. Supporting global C2X and Wi-Fi standards, the TEF510x integrates 802.11p modem functionality on one chip.

The TEF510x RF transceiver meets Japanese 760 MHz C2X requirements, US and European (5.9 GHz) as well as Wi-Fi and DSRC (5.8 GHz) specifications. It will be released for automotive production in 2015 and is expected to be available to consumers as early as 2016.

Together with the NXP/Cohda Wireless SAF510x baseband processor, that uses software-defined radio technology, the RoadLINK chip provides fast, accurate and reliable communication to and from the vehicle. RoadLINK, NXP asserts, gets safety-critical information to the driver significantly faster than current, conventional applications can.

Japanese-based company ALPS Electric is already using products from NXP's RoadLINK range to deliver in-car applications.

“Our chips enable OEMs to utilise a unique software-defined radio approach, to deploy global solutions based on a single hardware platform with end-of-line configurability,” said Thomas Hinz, senior product marketing manager, RoadLINK, NXP Semiconductors. “It’s the only solution that has been field proven in simTD and Safety Pilot, and which easily exceeds all of emerging Car-to-Car minimum performance requirements. It’s fast, it works over extended distances and it has the features to fully realise the potential of C2X technology.

Features of the TEF510x include;

RF-Transceiver for global C2X standards, covering Europe, US and Japan, as well as DSRC and Wi-Fi (802.11abgn) standards

Support for various antenna configurations and diversity schemes

Together with SAF510x, enabling 802.11p reception performance and communication range for mobility use cases even in non-line-of-sight conditions

AEC-Q100 qualification scheduled for 2015.
