This application note describes a method for connecting the LXT901 or LXT907 Ethernet Interface Adapter to the Motorola MC68EN360 Quad Integrated Communications Controller (QUICC) with Ethernet capability. The QUICC/LXT901 combination makes designing routers, bridges, print servers and other, similar products simple and fast. The LXT901 and LXT907 devices have advanced features that make design and fabrication faster and cheaper than typical competitors’ products. These two devices meet all of the Motorola QUICC design requirements with minimal external circuitry needed to use the MC68EN360 features. Either of these devices gives the lowest cost, highest performance possible with the Motorola QUICC.

Features
• Glueless interface to the MC68EN360 QUICC controller in 10 Mbps Ethernet/IEEE 802.3 LAN with either twisted- pair connection or AUI transceiver
• Integrated filters make design faster, fabrication cheaper
• Integrated LED drivers for operation monitoring
• Supports full duplex operation
• Automatic port selection makes choosing between the twisted-pair and AUI options seamless
