MTD655

www.DataSheet4U.com MYSON TECHNOLOGY FEATURES IEEE802.3 Clause 9 and IEEE802.3u Cluse 27 compliant. Provide 4 RMII (Reduced Media Independent Interface) ports and 1 MII port. 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 logic, theoretically can stack to 6 units and up) . 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. MTD655 5 Port 10M/100M Hub With 2 port Switch GENERAL DESCRIPTION The MTD655 is a highly integrated, 10M/ 100M dual speed hub with build_in 2 port switch. Support 4 RMII ports and 1 MII port for 10M/ 100M operation, and meet 100M_hub class_2 spec when connect with external PHYceivers. The MTD655 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 low cost asynchronous high speed SRAM (128k*8) one pcs only for packet buff...
