The SONICTM -16 (Systems-Oriented Network Interface Controller) is a second-generation Ethernet Controller designed to meet the demands of today's high-speed 16-bit systems Its system interface operates with a high speed DMA that typically consumes less than 8% 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-16 offers maximum flexibility in a variety of environments from PC-oriented adapters to high-speed motherboard designs Furthermore the SONIC-16 integrates a fully-compatible IEEE 802 3 Encoder Decoder (ENDEC) allowing for a simple 2-chip solution for Ethernet when the SONIC-16 is paired with the DP8392 Coaxial Transceiver Interface
