SN65C3221PWR Frequently Asked Questions (FAQs)

  • The maximum cable length supported by the SN65C3221PWR is approximately 100 meters, depending on the cable quality and the transmission rate.
  • The SN65C3221PWR can be configured for half-duplex or full-duplex operation by setting the HDX pin high or low, respectively. A high level on the HDX pin enables half-duplex operation, while a low level enables full-duplex operation.
  • The EN (enable) pin is used to enable or disable the transceiver. When the EN pin is high, the transceiver is enabled, and when it is low, the transceiver is disabled.
  • In a point-to-point connection, the transmit signal (TXD) from the transmitter is connected to the receive signal (RXD) of the receiver, and the transmit signal (TXD) from the receiver is connected to the receive signal (RXD) of the transmitter.
  • The recommended termination scheme for the SN65C3221PWR is a 100-ohm differential termination resistor at the transmitter output and a 100-ohm differential termination resistor at the receiver input.
