SP491CN-L Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the SP491CN-L is -40°C to +85°C.
  • To ensure reliable data transmission, ensure that the transmitter and receiver are properly terminated, and the transmission line is properly matched to the characteristic impedance of the device (100 ohms for the SP491CN-L).
  • The maximum cable length supported by the SP491CN-L depends on the data rate and cable characteristics. As a general guideline, the maximum cable length is approximately 100 meters at 100 Mbps.
  • To minimize EMI, use shielded cables, keep the transmitter and receiver close together, and ensure proper grounding of the device. Additionally, use EMI filters or common-mode chokes if necessary.
  • The power consumption of the SP491CN-L is typically around 150 mW (30 mA at 5V) when transmitting at 100 Mbps.
