AM79C982 General Description
The basic Integrated Multiport Repeater (bIMR™) chip is a VLSI circuit that provides a system-level solution to designing a compliant 802.3 repeater incorporating 10BASE-T transceivers. The device integrates the Repeater functions specified by Section 9 of the IEEE 802.3 standard and twisted-pair Transceiver functions complying to the 10BASE-T standard. The Am79C982-4 provides four and the Am79C982-8 provides eight integral twisted-pair medium attachment units (MAUs), and an attachment unit interface (AUI) port in an 84-pin plastic leaded chip carrier (PLCC).
A network based on the 10BASE-T standard uses unshielded twisted-pair cables, therefore providing an economical solution to networking by allowing the use of low-cost unshielded twisted-pair (UTP) cable or existing telephone wiring.
The total number of ports per repeater unit can be increased by connecting multiple bIMR devices through their expansion ports, hence minimizing the total cost per repeater port. Furthermore, a general-purpose attachment unit interface (AUI) provides connection capability to 10BASE-5 (Ethernet) and 10BASE-2 (Cheapernet) coaxial networks, as well as 10BASE-F and/or Fiber Optic Inter-Repeater Link (FOIRL) fiber segments. Network management and test functions are provided through TTL-compatible I/O pins.
The device is fabricated in CMOS technology and requires a single +5 V supply.
