Typical Setup
shows a typical test setup for standard operation of the LXD9785/9785E PQFP MII Demo
Board. The Demo Board plugs into a SmartBits Advanced Multi-port Performance Test Box via
eight standard 40-pin MII cables (not included on the board). Eight external NIC cards directly
connect to the SmartBits test box and plug into the Demo Board through fiber-module connectors.
Each port’s operation speed is set globally via hardware or individually via the MDIO for
evaluation of 100 Mbps capabilities using all eight ports.
