ISO1176TEVM Datasheet PDF - TI

●ISO1176TEVM is an evaluation module used to evaluate ISO1176T PROFIBUS transceiver. ISO1176T is an isolated differential line transceiver with integrated oscillator outputs that provide the primary voltage for an isolation transformer. The device is ideal for long transmission lines because the ground loop is broken to allow the device to operate with a much larger common mode voltage range. The symmetrical isolation barrier of each device is tested to provide 4242V peak of isolation per VDE for 60 seconds between the line transceiver and the logic level interface. The EVM can be used to evaluate the device parameters while acting as a guide for the board layout. The board alllows for the connection of 50ohm coaxial cables via QuiteZone connectors. It also provides easy connection points for oscilloscope probes. Banana jacks are provided for the connection of a dc power supply. These features provide the designer with a tool for evaluation and the successful design of an end product.
