| AM7996EVAL-HW Ethernet/Cheapernet Transceiver Evaluation Kit DISTINCTIVE CHARACTERISTICS s Advanced Micro Devices Connects the standard AUI port interface to 10BASE-2 (Cheapernet) connector. Jumper selectable Signal Quality Error (SQE) test allows evaluation in both node and repeater applications. s s Self contained board facilitates rapid evaluation of the AUI -to-coax system block, and demonstrates optimal analog design criteria. GENERAL DESCRIPTION The AM7996EVAL-HW board is a self contained module that implements all the functions of a Medium Attachment Unit (MAU) for IEEE 802.3 10BASE-2 (Cheapernet). This 3"x3" board can be used to connect any AUI port interface to the `thin' coaxial cable used in Cheapernet networks. This system permits the network designer to monitor signals on the card to increase his understanding of IEEE 802.3 standards and conventions. A jumper selectable SQE test enable/disable lets the board function in both user node or network repeater applications. In addition, optimal PC board layout is employed. The AM7996EVAL-HW kit comes complete with schematics, application notes, and coaxial cable connection hardware.
