SN65C3221PWR datasheet by Texas Instruments

SN65C3221PWR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65C3221PWR?
  The maximum cable length supported by the SN65C3221PWR is approximately 100 meters, depending on the cable quality and the transmission rate.
• How do I configure the SN65C3221PWR for half-duplex or full-duplex operation?
  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.
• What is the purpose of the EN pin on the SN65C3221PWR?
  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.
• How do I handle the transmit and receive signals in a point-to-point connection using the SN65C3221PWR?
  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.
• What is the recommended termination scheme for the SN65C3221PWR?
  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.
