TJF1052IT Part Attribute
- Description The TJF1052i is a high-speed CAN transceiver that provides a galvanically isolatedinterface between a Controller Area Network (CAN) protocol controller and the physicaltwo-wire CAN bus. The TJF1052i is specifically targeted at industrial applications, wheregalvanic isolation barriers are needed between the high- and low-voltage parts. Safety: Isolation is required for safety reasons, eg. to protect humans from electric shockor to prevent the electronics being damaged by high voltages. Signal integrity: The isolator uses proprietary capacitive isolation technology to transmitand receive CAN signals. This technology enables more reliable data communications innoisy environments, such as electric pumps, elevators or industrial equipment. Performance: The transceiver is designed for high-speed CAN applications, supplyingthe differential transmit and receive capability to a CAN protocol controller in amicrocontroller. Integrating the galvanic isolation along with the transceiver in theTJF1052i removes the need for stand-alone isolation. It also improves reliability andsystem performance parameters such as loop delay. The TJF1052i belongs to the third generation of high-speed CAN transceivers from NXPSemiconductors, offering significant improvements over first- and second-generationdevices. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStaticDischarge (ESD) performance, and also features ideal passive behavior to the CAN buswhen the transceiver supply voltage is off. The TJF1052i implements the CAN physical layer as defined in the current ISO11898 standard(ISO11898-2:2003). Pending the release of the updated version of ISO11898-2:2016including CAN FD and SAE J2284-4/5, additional timing parameters defining loop delaysymmetry are specified. This implementation enables reliable communication in the CAN FDfast phase at data rates up to 5 Mbit/s. The TJF1052i is an excellent choice for all types of industrial CAN networks whereisolation is required for safety reasons or to enhance signal integrity in noisyenvironments.
