The SP3508 Evaluation Board is designed to analyze the SP3508 multi-protocol transceivers. The evaluation board provides access points to all of the driver and receiver I/O pins so that the user can measure electrical characteristics and waveforms of each signal. The SP3508 Evaluation Board also includes a DB-25 serial port connector which is configured to a EIA-530 pinout. This allows easy connections to other DTE or DCE systems as well as network analyzers. The evaluation board also has a set of jumpers to allow the user to select the mode of operation and test the data latch feature. Furthermore, the SP3508 Evaluation Board provides the means to test both local and remote driver/receiver Loopback as well as evaluate the SP3508 in a DCE or DTE configuration. This Manual is split into sections to give the user the information necessary to perform a thorough evaluation of the SP3508. The Board Schematic and Layout section describes the I/O pins, the jumpers and the other components used on the evaluation board. The board schematic, layout diagram and DB-25 connector are also covered in the Board Schematic and Layout section. The Using the SP3508 Evaluation Board section details the configuration of the SP3508 evaluation board for parametric testing.
