TECHNOLOGY
(Preliminary)
16 Port 10M/100M Ethernet Switch
FEATURES
GENERAL DESCRIPTION
• IEEE802.3 and IEEE802.3u compliant.
• Provide 16 RMII (Reduced Media Independent
Interface) ports.
• Programmable 1K/8K MAC addresses filtering
database.
• 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.
• 4MB/2MB packet buffer with SGRAM/SDRAM
flexible memory interface.
• Port VLAN/trunking.
• Link/Rx activity, packet buffer utilization LED
display.
• 83MHz for non-blocking 16 port switch.
• Build in internal/external memory test function.
• 208 pin PQFP package, 3.3V operation volt-
age.
The MTD516 complies fully with the
IEEE802.3, 802.3u and 802.3x specifications and
is a non-blocking 16 port 10M/100M Ethernet
switch device.
Support 16 RMII ports for 10M/100M oper-
ation. 4MB memory interface provides maximum
2730 packet buffers for Ethernet packet buffering.
Up to 8192 address entrys are provided by the
MTD516, and the MTD516 use full Ethernet
address compare algorithm to minimize hashing
collision events.
The MTD516 provides EEPROM interface
to config port trunking, port VLAN, static entry,
802.3x flow control threshold, flooding port,
broadcast control threshold. Each MTD516 ports
support 10M/100M auto-negotiation by MII man-
agement interface.
The MTD516 also provides 2 pins for Link/
RX activity, packet buffer utilization LED display
function.
