NXP's TJA1080A Transceiver Passes the FlexRay Physical Layer Conformance Test

(Product News, 12 Mar 2008)

NXP Semiconductors' TJA1080A transceiver has passed the FlexRay Physical Layer Conformance Test, the industry standard for FlexRay products, making it the first transceiver to comply with this test.

"The TJA1080A transceiver addresses car manufacturers' need for faster, fault-tolerant communication systems which are flexible and scalable. Compliance to the FlexRay Physical Conformance Test is an important step in the proliferation of the FlexRay standard in the automotive industry," says Rob Hoeben, FlexRay Marketing Manager, NXP. "For our customers, this step means faster development times and fewer issues in production later. NXP is currently the only semiconductor supplier that can provide full compliance in a FlexRay solution that meets the industry standard."

With the high-speed FlexRay network communications system, carmakers can introduce advanced features that are transforming safety and comfort in the car. Aimed primarily at communication systems from 1Mbps to 10Mbps, the TJA1080A provides an advanced interface between the protocol controller and the physical bus in a FlexRay network. FlexRay is the first networking standard to enable these features, compared to existing networking standards such as CAN and LIN. It can be configured as an active star or node transceiver.

Moreover, the TJA1080A is fully TJA1080-compatible and there are no software adaptations necessary when switching from the TJA1080 to TJA1080A. Secure communications on the FlexRay network system are assured through active monitoring of system performance using dedicated error and status information, readable by any microcontroller. The device also monitors internal voltage and temperature and supports the mode control used in NXP's TJA1055 and TJA1041 CAN transceivers. A Bus Guardian interface enables the TJA1080A to be used in systems that require additional supervisions. The transceiver's excellent EMC performance is complemented by high ESD protection.

The TJA1080A transceiver delivers a number of significant enhancements over TJA1080, its predecessor:
- Improved power-on reset behavior
- Fully conforms to Electrical-Physical Layer V2.1
- Upgraded transmitter circuit to reduce emission on bus lines
- Enhanced receiver circuit—higher RF immunity, up to 70ns minimum bit time
