Product Review
Chapter 1 Product Overview
1.1 Overview
The ADM6996L 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 is
intended for applications to stand alone bridge for low cost SOHO market such as 5Port,
Router application.
ADM6996L provides most advance function 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 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 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 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 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 to use on Building
Internet access to prevent multiple users sharing one port traffic.
