TCAN1042HGDQ1 datasheet by Texas Instruments

TCAN1042HGDQ1 Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the TCAN1042HGDQ1?
  The maximum cable length supported by the TCAN1042HGDQ1 is 40 meters, assuming a 120-ohm twisted-pair cable with a maximum propagation delay of 5 ns/m.
• How do I ensure electromagnetic compatibility (EMC) with the TCAN1042HGDQ1?
  To ensure EMC, follow proper PCB layout guidelines, use a common-mode choke, and add shielding to the CAN bus cables. Additionally, ensure that the device is properly grounded and decoupled.
• What is the recommended termination scheme for the TCAN1042HGDQ1?
  The recommended termination scheme is a 120-ohm resistor at each end of the CAN bus, with a common-mode choke in series with the resistor to reduce electromagnetic emissions.
• How do I handle bus faults and error detection with the TCAN1042HGDQ1?
  The TCAN1042HGDQ1 has built-in error detection and fault-tolerant features, including bit-stuffing error detection, CRC error detection, and bus-off detection. Implement a fault-tolerant CAN protocol, such as ISO 11898, to handle bus faults and errors.
• What is the maximum data rate supported by the TCAN1042HGDQ1?
  The TCAN1042HGDQ1 supports data rates up to 1 Mbps, making it suitable for high-speed CAN applications.
