DS8921ATMX/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-speed PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using impedance-controlled traces.
  • The DS8921ATMX/NOPB has a thermal pad on the bottom of the package, which should be connected to a solid ground plane on the PCB to dissipate heat. Additionally, ensure good airflow around the device and consider using a heat sink if necessary.
  • The recommended power-up sequence is to apply VCC first, followed by VEE, and then the input signals. This ensures that the device powers up correctly and minimizes the risk of latch-up or damage.
  • Start by checking the power supply voltages, ensuring they are within the recommended range. Then, verify the input signals and clock frequencies are correct. Use an oscilloscope to check the output signals and look for any signs of oscillation or instability. If issues persist, consult the datasheet and application notes for further guidance.
  • The DS8921ATMX/NOPB is not specifically designed or tested for radiation hardness, so it's not recommended for use in radiation-hardened applications. Texas Instruments offers other products that are designed and tested for radiation hardness, such as the RH1080 and RH1081.
