SN65LBC184DG4 datasheet by Texas Instruments

SN65LBC184DG4 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the SN65LBC184DG4 to minimize EMI and ensure signal integrity?
  Texas Instruments provides a recommended PCB layout in the application note SLVAE04, which includes guidelines for trace routing, component placement, and grounding to minimize EMI and ensure signal integrity.
• How do I choose the correct termination resistors for the SN65LBC184DG4?
  The termination resistors should be chosen based on the transmission line impedance and the signal frequency. A good starting point is to use 50-ohm resistors for most applications, but the optimal value may need to be adjusted based on the specific system requirements.
• What is the maximum cable length supported by the SN65LBC184DG4?
  The maximum cable length supported by the SN65LBC184DG4 depends on the signal frequency, cable type, and system requirements. As a general guideline, the device can support cable lengths up to 10 meters at 100 Mbps, but this may need to be derated based on the specific system requirements.
• How do I ensure that the SN65LBC184DG4 is properly powered and decoupled?
  The SN65LBC184DG4 requires a stable power supply with adequate decoupling capacitors to ensure proper operation. A minimum of 0.1 uF decoupling capacitor should be placed close to the device, and additional capacitors may be required depending on the system requirements.
• What are the common failure modes of the SN65LBC184DG4 and how can they be prevented?
  Common failure modes of the SN65LBC184DG4 include overvoltage, overcurrent, and ESD damage. These can be prevented by ensuring proper power supply and signal routing, using adequate protection devices such as TVS diodes, and following proper handling and storage procedures.
