The maximum cable length supported by the TJA1043TK is dependent on the specific application and the type of cable used. However, as a general guideline, NXP recommends a maximum cable length of 40 meters for a 100 Mbps Fast Mode connection and 20 meters for a 1000 Mbps Gigabit connection.
The TJA1043TK has built-in features to minimize EMI and ensure EMC compliance, including a high-frequency common-mode choke, a low-pass filter, and a shielded pin for the CANH and CANL signals. Additionally, the device is designed to meet the requirements of the ISO 11898-2 standard for CAN physical layer transceivers.
The TJA1043TK has a typical power consumption of 70 mA in normal mode and 10 μA in standby mode. The power consumption can be further reduced by using the device's low-power mode, which can be enabled through the EN pin. The power consumption of the TJA1043TK should be considered as part of the overall system power budget, and designers should ensure that the device is properly powered and decoupled to minimize power noise and ensure reliable operation.
The TJA1043TK has built-in fault detection and error handling mechanisms, including detection of bus faults, such as short circuits, and error detection, such as bit errors and CRC errors. The device also has a fault-tolerant mode that allows it to continue operating even in the presence of faults, ensuring that the system remains operational and minimizing downtime.
The TJA1043TK has an operating temperature range of -40°C to 125°C, making it suitable for use in a wide range of applications, including automotive and industrial systems. The device's reliability is ensured through its robust design and manufacturing process, which includes extensive testing and qualification to ensure that it meets the requirements of the automotive and industrial markets.
