CAN transceiver family supports CAN FD, offers chokeless EMC performance
Mantis (TJA1044T and TJA1057T) and Mantis GT (TJA1044GT and TJA1057GT) offer a feature set targeting 12 V automotive applications and deliver excellent EMC performance, with the high-end “GT” variant guaranteeing critical parameters for CAN FD (Flexible Data rate) networks. All members of the Mantis family are dual-sourced from locations in the Netherlands and Singapore to provide a secure manufacturing base.
With the market demanding continued productivity of basic CAN functions, Mantis offers a feature set tailored to fulfill the requirements of mainstream automotive applications. For example, it is EMC compliant up to 2 Mbps, according to the “Hardware Requirements for LIN, CAN and FlexRay Interfaces in Automotive Application – Audi, BMW, Daimler, Porsche, Volkswagen – Revision 1.3 / 2012". In particular, Mantis takes a step forward by uniquely meeting today’s EMC emission limits at 500 kbps without requiring a common-mode choke – and with a choke, these same limits can be met at data rates of 2 Mbps in CAN FD networks. In addition, the devices’ bus pins are tolerant to ±42 V, and ESD meets automotive requirements of 6 kV (IEC-61004-2) with typical standby currents of 10 µA.
“As the industry continues to innovate to extract more from traditional CAN networks, Mantis GT addresses many of the concerns around CAN FD", said Toni Versluijs, vice president and general manager, in-vehicle networking business, NXP Semiconductors. "With this product, NXP has shown that it’s possible to also achieve excellent EMC performance at speeds of 2 Mbps and beyond.”
Mantis GT also introduces loop delay symmetry, a new parameter which guarantees the integrity of CAN communication is preserved at higher speeds, resulting in a transceiver that is optimized for data rates of 2 Mbps and over. This is an important development for the industry’s adoption of CAN FD, which depends on semiconductor solutions being able to support CAN communication at higher speeds.
