1. GENERAL DESCRIPTION
The ACD82124 is a single chip implementation of a 24
port 10/100 Ethernet switch system intended for IEEE
802.3 and 802.3u compatible networks. The device
includes 24 independent 10/100 MACs. Each MAC
interfaces with an external PMD/PHY device through a
standard MII interface. Speed can be automatically
configured through the MDIO port. Each port can op-
erate at either 10Mbps or 100Mbps. The core logic of
the ACD82124, implemented with patent pending
BASIQ (Bandwidth Assured Switching with Intelligent
Queuing) technology, can simultaneously process 24
asynchronous 10/100Mbps port traffic. The Queue
Manager inside the ACD82124 provides the capability
of routing traffic with the same order of sequence,
without any packet loss.
A complete 24 port 10/100 switch can be built with the
use of the ACD82124, 10/100 PHY and ASRAM. The
MAC addresses can be expanded from the built-in 2K
to 11K by the use of ACD’s external ARL chip
(ACD80800 Address Resolution Logic). Advanced net-
work management features can be supported with the
use of ACD’s MIB (ACD80900 Management Informa-
tion Base) chip.
