SP3483EN-L Frequently Asked Questions (FAQs)

  • The recommended layout and routing for the SP3483EN-L involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. A 4-layer PCB with a dedicated ground plane is recommended.
  • To optimize the performance of the SP3483EN-L in noisy environments, use a common-mode choke or a ferrite bead in series with the VCC pin to filter out high-frequency noise. Additionally, use a capacitor in parallel with the VCC pin to decouple the power supply.
  • The maximum cable length supported by the SP3483EN-L depends on the baud rate and the type of cable used. As a general guideline, the maximum cable length is approximately 100 meters at 9600 bps and 10 meters at 921600 bps.
  • The SP3483EN-L supports RTS/CTS flow control. To implement flow control, connect the RTS pin to the CTS pin of the remote device, and the CTS pin to the RTS pin of the remote device. The device will automatically assert RTS when the transmit FIFO is full, and de-assert RTS when the transmit FIFO has space available.
  • The maximum power consumption of the SP3483EN-L is approximately 120 mA at 3.3V, assuming a 921600 bps data rate and a 100% duty cycle. However, the actual power consumption may vary depending on the specific application and operating conditions.
