Product Summary
The mqe9pd-1880-t7 single-port 10/100 mbps phy transceiver is an ieee compliant fastethernet phy transceiver that directly supports both 100base-tx and 10base-t applications. itprovides a media independent interface (mii) for easy attachment to 10/100 media accesscontrollers (macs). both full and half-duplex operation at 10 mbps and 100 mbps is supported.operation mode can be set to auto-negotiation, parallel detection, or manual control. the device ispowered from a single 3.3v power supply. It is ideal for: (1)combination 10base-t/100base-tx network interface cards (nics); (2)wireless access points; (3)network printers; (4)10/100 personal computer memory card international association (pcmcia)cards; (5)cable modems and set-top boxes.
