1.1
The Samurai-6M/6MX (ADM6996M/MX) is a high performance, low cost, highly integrated (Controller, PHY and
Memory) four 10M/100M auto-detect Half/Full duplex switch ports with TX/FX interfaces and two MII port with one
MII supporting GPSI/RMII. The Samurai-6M/6MX (ADM6996M/MX) is intended for applications such as stand
alone bridges for the low cost SOHO markets such as 5-port switches and router applications. The Samurai-6MX
(ADM6996MX) is the environmentally friendly “green” package version.
The Samurai-6M/6MX (ADM6996M/MX) provides 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 functions to meet
customer requests on switch demand.
The Samurai-6M/6MX (ADM6996M/MX) also supports back pressure in Half-Duplex mode and the 802.3x Flow
Control Pause packet in Full-Duplex mode to prevent packet loss when buffers are full. When Back Pressure is
enabled, and there is no receive buffer available for the incoming packet, the Samurai-6M/6MX (ADM6996M/MX)
will issue a JAM pattern on the receiving port in Half Duplex mode and issue the 802.3x Pause packet back to the
receiving end in Full Duplex mode.
The built-in SRAM used for the packet buffer is divided into 256 bytes per block to achieve the optimized memory
utilization through complicated link lists on packets with various lengths.
The Samurai-6M/6MX (ADM6996M/MX) also supports priority features using Port-Based, VLAN and IP TOS field
checking. Users can easily set different priority modes in individual ports, through a small low-cost micro controller
when initializing or configuring on-the-fly. Each output port supports four queues in the way of fixed N: 1 fairness
queuing to fit the bandwidth demand on various types of packets such as Voice, Video and Data. 802.1Q,
Tag/Untag, and up to 16 groups of VLAN are also supported.
An intelligent address recognition algorithm allows Samurai-6M/6MX (ADM6996M/MX) to recognize up to 2K
different MAC addresses and enables filtering and forwarding at full wire speed.
Port MAC address Locking function is also supported by Samurai-6M/6MX (ADM6996M/MX) to use on building
Internet access to prevent multiple users sharing one port.
