... Advanced 10/100 Repeater with Integrated Management The LXT9880 is the next-generation repeater family, integrated with eight 10/100 transceivers. The LXT9880 is compatible with previous generations of Intel repeaters from the LXT980 and LXT918 families. Eight ports directly support 100BASE-TX/10BASE-T copper media. Two additional Media Independent Interface (MII) ports (10/100 Mbps selectable) connect to Media Access Controllers (MACs) for bridge/switch applications ...
