Description
The SP336 Evaluation Board is designed to analyze the SP336 multi-protocol transceiver.
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 evaluation board
also has a switch to allow the user to select the mode of operation and slew control.
Furthermore, the SP336 Evaluation Board provides the means to test both local and remote
driver/receiver loop-back.
This Manual is split into sections to give the user the information necessary to perform a
thorough evaluation of the SP336. The “Layout” section describes the I/O pins, jumpers and the
other components used on the evaluation board. The layout diagram is also covered. The “Using
the SP336 Evaluation Board” section details the configuration of the SP336 evaluation board for
parametric testing.
