GENERAL DESCRIPTION
MX98216EC is a stand-alone 10/100M Ethernet switch
controller with SRAM embedded which saves at least
one 64KX64 SRAM cost. Any standalone desktop or
enterprising Ethernet switches can be achieved by
simply combining MX98216EC and quad/octal physical
devices.
All 16 ports are full duplex capable to provide
dedicated 20/200M bandwidth connections each port.
MX98216EC
basically
supports
store-and-forward
switching scheme with two address entry tables, 4K size
each.
The function modules integrated in controller
include 16-port half/full-duplex compatible media access
controller with RMII interface, address resolution logic
(ARL) for address learning, filtering, recognition, priority
queue manager, port base VLAN.
It fully complies with
IEEE
Std.
802.3/802.3u/802.1q
specifications
and
supports
MDC/MDIO
interface
for
physical
layer
management with industrial standard physical devices.
The
switch
architecture
adopting
dynamic
buffer
management shared by 16 ports can reach full-line
speed of high performance application.
To save
system cost, single 50Mhz clock is for RMII and system
requirement.
MX98216EC
proceeds
in
advanced
foundry and smaller package which consumes lower
power dissipation.
The smart features with low power CPU or EEPROM
are for system configuration and ALR access required.
Also, it emphasizes at
Class of Service (CoS) which
extracts various packet types in appropriate forwarding
scheme.
Now, Voice over IP (VoIP) is applied the
feature for cutting voice packet latency and promise the
quality of service.
In addition, port-base VLAN is
another valuable feature for the switches.
MX98216EC
offers 12 groups with port overlapping allowed.
The
feature can add on more security and data flow in the
same switch with different groups should get connection
through router.
The powerful switching architecture
and robust design can easily reach high performance,
non-blocking data flow.
Head-of-line blocking prevents switch performance, and
operation defective from other port impacts. The switch
architecture
provides
a
clean
port
independent
operation.
It guarantees port transmission or receive
is not affected by other ports.
Moreover, user can discard broadcast packets regarding
the threshold of system overload.
This prevents
potential broadcast storming from abnormal events.
After buffer fullness drops in the safe margin, the switch
controller jumps into flow control state to allow physical
ports work as normal condition.
MX98216EC provides self on test as soon as power on
or reset. It will detect all buffer memory and address
table and others.
If defective, LED is automatically on.
Several LEDs are defined in switch controller like status
of broadcast storm, packet loss, and buffer full.
