SP336E Evaluation Board Manual 11-23-10 Rev 2.1 Features Easy Evaluation of the SP336E Transceiver RS-232 and RS-485 Protocols Local or Remote Loop Back testing 10Mbps Differential Transmission Rates Test point for cable or jumper loop-back 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.
