Product Summary
The LXT980QC is a 5-port 10/100 Class II Repeater that is fully compliant with IEEE 802.3 standards. Four ports directly support either 100BASE-TX/10BASE-T copper media or 100BASE-FX fiber media via pseudo-ECL (PECL) interfaces. The fifth port, a 10 or 100 Mbps Media Independent Interface (MII), connects to Media Access Controllers (MACs) for bridge/switch applications. At 100 Mbps, the LXT980QC can also be configured to interface to another PHY device.
