ISO35TDWR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10nF capacitor between VCC and GND, and a 100nF capacitor between AVCC and AGND.
  • Use a shielded enclosure, keep the device away from high-frequency sources, and use a common-mode choke on the input lines. Ensure that the PCB layout is designed to minimize radiation and susceptibility.
  • The maximum cable length depends on the data rate and the type of cable used. As a general guideline, use a cable length of up to 10 meters for a data rate of 100 Mbps, and up to 5 meters for a data rate of 1 Gbps.
  • Power up the device in the following sequence: VCC, AVCC, and then the digital inputs. Power down in the reverse sequence. Ensure that the power supplies are stable and within the recommended voltage range before applying digital inputs.
  • Use a heat sink with a thermal resistance of less than 10°C/W. Ensure good airflow around the device, and avoid blocking the airflow with components or cables. Use thermal interface material (TIM) to improve heat transfer between the device and the heat sink.
