SP3508 Evaluation Board Manual

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.
