Universal Demo Board for 10BASE-T and AUI Applications — LDB901
Developer Manual

1.0
General Description
The LDB901 Demo Board is a complete working platform that allows system designers to test
device performance and functionality prior to board prototyping. The LDB901 can be used to
evaluate the LXT901, LXT907, LXT901A, LXT907A or LXT908 Universal Ethernet Transceivers
with a few minor modifications to the board.
The LDB901 is designed to interface most standard controllers to either 10BASE-T cable or
10BASE-2/10BASE-5 Attachment Unit Interface (AUI) drop cable. The Demo Board supports
standard 10Mbps operation or full duplex 20Mbps operation. The LDB901 is configured with a
complete set of LED status indicators for major functions. A single 5V supply is required for
operation with provision for conversion to 3.3V.
This document describes typical Demo Board setup and operating procedures. Before using the
Demo Board, review the applicable Universal Ethernet Transceiver data sheet for device
functionality and specifications.
