1.1
The ADM6996L/LX is a high performance, low cost, highly integration (Controller, PHY and Memory) five-port
10/100 Mbps TX/FX plus one 10/100 MAC port Ethernet switch controller with all ports supporting 10/100 Mbps
Full/Half duplex. The ADM6996L/LX is intended for applications to stand alone bridge for low cost SOHO market
such as 5Port, Router application. The ADM6996LX is the environmentally friendly “green” package version.
ADM6996L/LX provides most advanced functions such as:802.1p(Q.O.S.), 802.1q(VLAN), Port MAC address
Locking, Management, Port Status, TP Auto-MDIX, 25M Crystal & Extra MII port function to meet customer
request on Switch demand.
The ADM6996L/LX also supports Back Pressure in Half-Duplex mode and 802.3x Flow Control Pause packet in
Full-Duplex mode to prevent packet lost when buffer full. When Back Pressure is enabled, and there is no receive
buffer available for the incoming packet, the ADM6996L/LX will issue a JAM pattern on the receiving port in Half
Duplex mode and transmit the 802.3x Pause packet back to receiving end in Full Duplex mode.
The built-in SRAM used for packet buffer and address learning table is divided into 256 bytes/block to achieve the
optimized memory utilization through complicated link list on packets with various lengths.
ADM6996L/LX also supports priority features by Port-Base, VLAN and IP TOS field checking. User can be easy
to set as different priority mode in individual port, through a small low-cost micro controller to initialize or on-the-
fly to configure. Each output port supports four queues in the way of fixed N: 1 fairness queuing to fit the bandwidth
demand on various types of packet such as Voice, Video and data. 802.1Q, Tag/Untag, and up to 16 groups of
VLAN also is supported.
An intelligent address recognition algorithm makes ADM6996L/LX to recognize up to 2048 different MAC
addresses and enables filtering and forwarding at full wire speed.
Port MAC address Locking function is also supported by ADM6996L/LX to use on Building Internet access to
prevent multiple users sharing one port traffic.
