MTD658E General Description
The MTD658E is a highly integrated, 10M/ 100M dual speed hub with build_in 2 port switch and 64k8 embedded ASRAM. Support 8 RMII ports for 10M/100M operation, and really meet 100M_hub class_2 spec when connect with external QPHYceivers.
The MTD658E provides two Inter-repeater stacking bus for 10M and 100M expansion each, easily stack to 4 units without any external arbitration logic. If using external arbitration logic and proper bus driver, can stack to 6 units and up.
The build_in 2 port switch, support 2k MAC addresses filtering, and use embedded asynchronous high speed SRAM (64k*8) for packet buffering. This 2 port switch can also be configured to be up_link switch when hub is under slave mode.
The MTD658E also support an simple and effective LED display function, provide 10M_col, 100M_col, and per port's partition status.
