Description

The DP83223 Twisted Pair Transceiver is an integrated circuit capable of driving and receiving three-level (MLT-3)
encoded datastreams. The DP83223 Transceiver is designed to interface directly with National Semiconductor's Fast Ethernet and FDDI Chip Sets or similar Physical Layer silicon allowing low cost data links over copper based media. The DP83223 allows links of up to 100 meters over Shielded Twisted Pair (Type-1A STP) and Category-5 datagrade Unshielded Twisted Pair (Cat-5UTP) or equivalent. The DP83223 is available in a 28 pinPLCC package and a 32 pin PQFP package.
