The SP50x Evaluation Board is designed to analyze the SP504 or SP505 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 SP50x 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.
