Low-Speed/Fault Tolerant CAN Transceiver

NI-XNET CAN Low-Speed/Fault-Tolerant hardware uses either the NXP TJA1054A or NXP TJA1055T Low-Speed/Fault-Tolerant transceiver.

NI PXI and PCI XNET interfaces revision E and higher use the TJA1055T transceiver, while revision D and lower use the TJA1054A transceiver.

To identify your PCI/PXI NI-XNET hardware revision, refer to the 19xxxx<rev>-4xL text on the green label in the top left corner on the secondary side of the board; <rev> indicates the hardware revision.

Both the TJA1054A and TJA1055T support baud rates up to 125 kbps. The transceiver can detect and automatically recover from the following CAN bus failures:
  • CAN_H wire interrupted
  • CAN_L wire interrupted
  • CAN_H short-circuited to battery
  • CAN_L short-circuited to battery
  • CAN_H short-circuited to VCC
  • CAN_L short-circuited to VCC
  • CAN_H short-circuited to ground
  • CAN_L short-circuited to ground
  • CAN_H and CAN_L mutually short-circuited

The TJA1054A and TJA1055T support advanced power management through a low-power sleep mode. Refer to the NI-XNET Session Interface:CAN:Transceiver State property for more information. For detailed specifications for the transceivers, refer to the NXP TJA1054 and NXP TJA1055T product data sheets.
