LXD9785 PQFP Demo Board with FPGA for SS-SMII (Fiber)-to-MII Conversion

2.4Typical Setup

Figure 2 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.
