General Description (Continued)
The MAC function (NIC) provides simple and efficient pack-
et transmission and reception control by means of unique
dual DMA channels and an internal FIFO Bus arbitration
and memory control logic are integrated to reduce board
cost and area overheads
SNIC used in conjunction with the DP8392 Coaxial Trans-
ceiver Interface (CTI) provides a comprehensive 2 chip solu-
tion for IEEE 8023 networks and is designed for easy inter-
face to the latest 10BASE-T transceivers
Due to the inherent constraints of CMOS processing isola-
tion is required at the differential signal interfaces for
10BASE5 and 10BASE2 applications Capacitive or induc-
tive isolation may be used
