DESCRIPTION

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.
