Description

The MTD505 complies fully with the IEEE802.3, 802.3u and 802.3x specifications and is a non-blocking 5 port 10M/100M Ethernet switch device.

Support 4 RMII and 1 MII/RMII ports for 10M/100M operation. 1MByte/2MBytes memory interface provides maximum 1365 packet buffers for Ethernet packet buffering. Up to 8192 address entrys are provided by the MTD505, and the MTD505 use full Ethernet address compare algorithm to minimize hashing collision events.

The MTD505 provides EEPROM interface to config port trunking, port VLAN, static entry, 802.3x flow control threshold, flooding port, broadcast control threshold. Each MTD505 port support 10/100M auto-negotiation by MDC/MDIO interface for connecting external PHY devices.

The MTD505 also provides 10 pins for Link/RX activity, packet buffer utilization LED display function.
