DP83223 Datasheet Twister High Speed Networking Transceiver Device

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: .. DP83223 April, 1997 DP83223 TWISTER High Speed Networking Transceiver.

General 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-5 UTP) or equivalent.

Key Features

  • s s s s s s s s s Compatible with ANSI X3.263 TP-PMD draft standard Allows use of Type 1 STP and Category 5 UTP cables Requires a single +5V supply Integrated transmitter and receiver with adaptive equalization circuit Isolated TX and RX power supplies for minimum noise coupling Loopback feature for board diagnostics Digitally Synthesized transmit signal transition time control for reduced EMI Programmable transmit voltage amplitude Suitable for 100BASE-TX Fast Ethernet and Twisted Pair FDDI app.
