描述 Description

The TJF1051 is a high-speed CAN transceiver that provides an interface between a Controller AreaNetwork (CAN) protocol controller and the physical two-wire CAN bus. The transceiver isdesigned for high-speed CAN industrial applications, providing differential transmit andreceive capability to (a microcontroller with) a CAN protocol controller.
The TJF1051 belongs to the third generation of high-speed CAN transceivers from NXPSemiconductors, offering significant improvements over first- and second-generationdevices such as the TJA1050. It offers improved ElectroMagnetic Compatibility (EMC) andElectroStatic Discharge (ESD) performance, and also features ideal passive behavior tothe CAN bus when the supply voltage is off. The TJF1051T/3 can be interfaced directly tomicrocontrollers with supply voltages from 3 V to 5 V.
The TJF1051 implements the CAN physical layer as defined in the current ISO11898 standard(ISO11898-2:2003, ISO11898-5:2007) and the pending updated version of ISO 11898-2:2016.Pending the release of the updated version of ISO11898-2:2016 including CAN FD and SAEJ2284-4/5, additional timing parameters defining loop delay symmetry are specified. Thisimplementation enables reliable communication in the CAN FD fast phase at data rates upto 5 Mbit/s.
These features make the TJF1051 an excellent choice for all types of HS-CAN networks, in nodesthat do not require a standby mode with wake-up capability via the bus.
