A good PCB layout for the TJA1020T/N1,118 involves keeping the transmitter and receiver lines as short as possible, using a ground plane, and minimizing electromagnetic interference (EMI) by keeping the transmitter and receiver lines away from each other and from other noisy signals.
To ensure reliable communication in noisy environments, use a common-mode choke or a ferrite bead to filter out electromagnetic interference (EMI), and consider using a shielded cable or a twisted pair cable to reduce electromagnetic radiation.
The maximum cable length supported by the TJA1020T/N1,118 depends on the specific application and the type of cable used. As a general guideline, the maximum cable length is typically around 40 meters for a twisted pair cable and 10 meters for a coaxial cable.
To troubleshoot issues with the TJA1020T/N1,118, start by checking the power supply voltage, then verify the transmitter and receiver connections, and finally, use an oscilloscope to check the signal quality and timing.
The TJA1020T/N1,118 is designed for low-to-medium speed data transmission up to 100 kbps. For high-speed data transmission, consider using a different transceiver chip or a dedicated high-speed transceiver IC.
