SN75188DR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN75188DR?
  The maximum cable length supported by the SN75188DR is dependent on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths of up to 100 meters (328 feet) at a data rate of 100 Mbps.
• How do I ensure signal integrity and minimize electromagnetic interference (EMI) when using the SN75188DR?
  To ensure signal integrity and minimize EMI, it is recommended to use a shielded cable, keep the cable away from noise sources, use a common-mode choke, and follow proper PCB layout and grounding techniques.
• What is the power consumption of the SN75188DR, and how can I reduce it?
  The power consumption of the SN75188DR is typically around 150 mA at 5 V. To reduce power consumption, consider using a lower supply voltage, reducing the clock frequency, or using the device's power-down mode.
• Can I use the SN75188DR for applications requiring isolation, and if so, how?
  Yes, the SN75188DR can be used for applications requiring isolation. You can use an isolation transformer or a digital isolator to provide electrical isolation between the transmitter and receiver sides.
• What are the key considerations for layout and routing when using the SN75188DR?
  When using the SN75188DR, it is essential to follow proper layout and routing guidelines to minimize signal reflections, crosstalk, and EMI. Keep the transmitter and receiver lines as short as possible, use a solid ground plane, and avoid routing signals near noise sources.
