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.
