SP508 Evaluation Board Manual

1

The SP508 Evaluation Board is designed to analyze the SP508 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 SP508

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 dip switches to allow the user to select the mode

of operation and test the data latch feature. The SP508 Evaluation Board Provides the means

to test both local and remote driver/receiver Loopback as well as evaluate the SP508 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 SP508. The Board Layout section describes the I/O pins, the Dip

switches and the other components used on the evaluation board. The board schematic,

layout diagram, list of materials and DB-25 connector are also covered in the Board Layout

section. The Using the SP508 Evaluation Board details the configuration of the SP508

evaluation board for parametric testing.
