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

1.0General Description

The LXD9785 PQFP MII Demo Board is an eight-port 100 Mbps Fast Ethernet Media Access Unit (MAU) that provides a working platform for evaluation of the LXT9785/9785E Fast Ethernet Octal Transceiver. All eight network ports provide a fiber interface for a 100BASE-FX connection.

The Demo Board allows system designers to test 100 Mbps Fiber link performance and register functionality using a standard MII interface prior to board prototyping. Two FPGAs convert the eight fiber (SS-SMII) interfaces on the LXT9785/9785E to eight standard MII interfaces. This conversion simplifies evaluation of the LXT9785/9785E, rendering it compatible with existing MII test equipment.

The Demo Board requires three external power supply inputs supplied by 2.5V and 3.3V power supplies.
