Texas InstrumentsISO1176EVMDevelopment Kits and Tools

The EVM can be used to evaluate device parameters while acting as a guide for board layout. The board allows the connection of a 50 ohm coaxial cable (via an SMA connector) to connect to instrumentation, or to 54-ohm controlled impedance cable of varying lengths (via a female header or Quietzone® connector). This provides the designer with a tool for evaluation and successful design of an end product. This EVM allows evaluation of the ISO1176 ProfiBus Transceiver. The EVM comes with a single transceiver installed on the circuit board (U1), but because it has been designed into the industry standard 176 footprint for 16-pin devices, other 176- footprint devices may be evaluated as well. Take care with regard to the isolated power and ground, as this is an isolating device. Power and ground for the Data/Control side of the device (pins D, R, DE, RE) can be completely isolated from power and ground for the Bus side of the device (pins A, B, ISODE). Note that this EVM is not intended for electromagnetic compatibility (EMC) tests.
