The TJF1051 is a high-speed CAN transceiver that provides an interface between a Controller Area
Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is
designed for high-speed CAN industrial applications, providing differential transmit and
receive capability to (a microcontroller with) a CAN protocol controller.
The TJF1051 belongs to the third generation of high-speed CAN transceivers from NXP
Semiconductors, offering significant improvements over first- and second-generation
devices such as the TJA1050. It offers improved ElectroMagnetic Compatibility (EMC) and
ElectroStatic Discharge (ESD) performance, and also features ideal passive behavior to
the CAN bus when the supply voltage is off. The TJF1051T/3 can be interfaced directly to
microcontrollers 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 SAE
J2284-4/5, additional timing parameters defining loop delay symmetry are specified. This
implementation enables reliable communication in the CAN FD fast phase at data rates up
to 5 Mbit/s.
These features make the TJF1051 an excellent choice for all types of HS-CAN networks, in nodes
that do not require a standby mode with wake-up capability via the bus.
