Description
ACD82124 is a single chip system integration of an entire 24 port Ethernet switch, specifically designed for networks compliance with IEEE 802.3 10Base-T standard. All active components of a 24 port Ethernet switch system, including the 10BASE-T transceivers, clock and data recovery circuitry, Manchester ENDEC, Media Access Control logic, Lookup Engine, Switch Fabric, and Switch Control logic are all integrated into a single semiconductor chip. ACD82124 can be used to build a desktop class 10BASE-T Ethernet switch system with very low cost and very short time-to-market cycle. To build a marketable Ethernet switch system using ACD82124 requires no more than a DC power supply, EMI/RFI filter/transformer modules, RJ45 connectors, LEDs, and LED drivers.
