TRS3221ECPW Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to route the differential pairs as close together as possible, with a minimum of 10 mils of separation between them.
  • The TRS3221ECPW requires a 100-ohm differential termination resistor at the receiver end, and a 50-ohm single-ended termination resistor at the transmitter end. Additionally, the datasheet recommends using a 10-ohm series resistor at the transmitter output.
  • The maximum cable length supported by the TRS3221ECPW is dependent on the specific application and the type of cable used. However, as a general guideline, Texas Instruments recommends keeping the cable length under 10 meters to ensure reliable operation.
  • To handle common-mode noise and EMI, Texas Instruments recommends using a common-mode choke or a ferrite bead in series with the differential pairs, and to ensure good PCB layout practices such as keeping the differential pairs close together and away from noise sources.
  • The recommended power-up sequence for the TRS3221ECPW is to power up the VCC supply first, followed by the VCCA supply. This ensures that the internal voltage regulators are properly initialized.
