MTD508 Datasheet | Myson Technology

FEATURES GENERAL DESCRIPTION The MTD508 plies fully with the IEEE802.3, 802.3u and 802.3x specifications and is a nonblocking 8-port 10M/100M Ethernet switch device. The MTD508 supports 8 RMII ports for 10M/100M operations. 1MBytes/2MBytes memory interface provides maximum 1365 packet buffers for Ethernet packet buffering. Up to 8192 address entries are provided by the MTD508, and the MTD508 uses full Ethernet address to pare algorithm for minimizing hashing collision events. The MTD508 provides EEPROM interface to configure port trunking, port VLAN, static entry, 802.3x flow control threshold, flooding port, broadcast control threshold. Each MTD508 port supports 10M/100M auto-negotiation by MDC/MDIO interface for connecting external PHY devices. The MTD508 also provides 10 pins for Link/RX activities, packet butter utilization LED display functoin. - IEEE802.3 and IEEE802.3u pliant. - Provides 8 RMII (Reduced Media Independent Interface) ports. - Programmable 1K/8K MAC addresses filtering. - Store and forward switching function and bad packet filtering function. - Optional back-pressure/802.3x flow control/ flooding control/broadcast control. - Optional EEPROM interface for advanced switch configurations. - 1MB/2MB SGRAM/SDRAM flexible memory interface. - Port VLAN/trunking. - Link/Rx activities, packet buffer utilization LED display. - 75MHz for non-blocking for 8-port switch operation. - Built-in interna/external memory test function. - 160-pin PQFP package, 3.3V operating voltage.
