1.1
The ADM6999G/GX is a high performance, low cost, and highly integration (Controller, PHY and Memory) eight-
port 10/100 Mbps TX/FX plus one 10/100/1000 GMII port Ethernet switch controller with all ports supporting
10/100 Mbps Full/Half duplex and Gigabit port support Full Duplex switch function. The ADM6999G/GX is
intended for applications to stand alone the bridge for low cost SOHO market such as 8+1G. The ADM6999GX is
the environmentally friendly “green” package version.
ADM6999G/GX 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 ninth Port (GMII) functions to meet
the customer’s requests on Switch demand.
The built-in 768K SRAM used for the packet buffer and address learning table is divided into 512 bytes/block to
achieve the optimized memory utilization through complicated link list on packets with various lengths.
ADM6999G/GX also supports priority features by Port-Base, VLAN and IP TOS field checking. Users can easily
set a 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 two 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 32 groups of
VLAN are also supported. ADM6999G/GX learns user to define 4 or 5 bits of VLAN ID.
An intelligent address recognition algorithm makes ADM6999G/GX 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 ADM6999G/GX to use on Building Internet access to
prevent multiple users share one port traffic.
