The SONIC-T (Systems-Oriented Network Interface Controller with Twisted Pair) is a second-generation Ethernet Controller designed to meet the demands of today's high-speed 32- and 16-bit systems Its system interface operates with a high speed DMA that typically consumes less than 5% of the bus bandwidth Selectable bus modes provide both big and little endian byte ordering and a clean interface to standard microprocessors The linked-list buffer management system of SONIC-T offers maximum flexibility in a variety of environments from PC-oriented adapters to high-speed motherboard designs Furthermore the SONIC-T integrates a fully-compatible IEEE 802 3 Encoder Decoder (ENDEC) and a Twisted Pair Interface which provide a one-chip solution for Ethernet when using 10BASE-T When using 10BASE2 or 10BASE5 the SONIC-T may be paired with the DP8392 Coaxial Transceiver Interface to achieve a simple 2-chip solution
