Texas Instruments RS485FLDPLXDRCEVM Transceiver Evaluation Module

Texas Instruments RS485FLDPLXDRCEVM Transceiver Evaluation Module (EVM) allows quick prototyping of the TI full-duplex ±70V tolerant RS-485 transceivers in the VSON (DRC) package. The board provides for testing of single and differential-ended communication with potential modifications. These modifications include changing the termination resistance or adding a common mode bias to the bus to simulate ground potential differences seen in systems with long cables that share a ground line with high current capacity. The board comes preinstalled with a Texas Instruments THVD2412DRCR, which allows full duplex communication at up to 250kbps powered by a 3V to 5.5V power connection on VCC. The board also supports the testing of systems with separate EARTH planes separate from the device ground reference plane.

Features

  • THVD2412 preinstalled onto the evaluation module
  • Four power-supply bulk decoupling capacitor pads for VCC, GND, and EARTH lines
  • Terminal block and header pin access to RS-485 bus signals
  • 0603 resistor pads available to create resistive links between GND and EARTH connections for VCC terminal
  • Indicator diodes for RX and TX data, as well as a power indicator diode

Applications

  • Motor drives
  • Factory automation and control
  • HVAC systems
  • Building automation
  • Grid infrastructure
  • Electricity meters
  • Process analytics
  • Video surveillance
