TECHNOLOGY

8 Port 10M/100M Hub With 2 port Switch

FEATURES

GENERAL DESCRIPTION

•

IEEE802.3 Clause 9 and IEEE802.3u Cluse 27

compliant.

Provide 8 RMII (Reduced Media Independent

Interface) ports.

Provide 2 inter_repeater stacking bus for 10M

and 100M port expansion each.

Support stacking to 4 units without any external

arbitration logic ( if use external arbitration

The MTD658 is a highly integrated, 10M/

100M dual speed hub with build_in 2 port switch.

Support 8 RMII ports for 10M/100M operation,

and really meet 100M_hub class_2 spec when

connect with external QPHYceivers.

The MTD658 provides two Inter-repeater

stacking bus for 10M and 100M expansion each,

easily stack to 4 units without any external arbi-

logic, theoretically can stack to 6 units and up) . tration logic. If using external arbitration logic and

•

Build_in 2 port switch controller, support up to

2048 MAC addresses filtering database.

Optional back_pressure flow control

Optional up_link_switch port function (in slave

hub), support 100FX 2km distance extension in

100FD mode.

Meet Class_2 repeater specification for

100M_hub.

Use simple and low cost asynchronous SRAM

(high speed ASRAM 128k*8 : one pcs only)

128 pin PQFP package, 5V operation voltage.

proper bus driver, can stack to 6 units and up.

The build_in 2 port switch, support 2k MAC

addresses filtering, and use low cost asynchro-

nous high speed SRAM (128k*8) one pcs only for

packet buffering. This 2 port switch can also be

configured to be up_link switch when hub is

under slave mode.

The MTD658 also support an simple and

effective LED display function, provide 10M_col,

100M_col, memory_test_fail, and per port’s parti-

tion status.
