1. General Description
The T71L6816A is a highly integrated sixteen-port 10Base-T/100Base-TX Ethernet switch
with RMII interface and is implemented in 0.18μm CMOS technology. The T71L6816A
supports a wide variety of switch features and provides flexible configurations at
maximum performance levels with lowest number of components.
This switch supports store-and-forward switching scheme with an external memory buffer
for incoming/outgoing packets and a built-in memory for address table. The T71L6816A use
the age-based memory architecture to fully utilize the acket buffer so that it can identify
up to 2048 different MAC addresses and enable the filtering and forwarding of packets
range from 64 bytes to 1522 bytes at the non-blocking wire speed, 148800 packets/sec at
64 bytes/packet.
The function modules integrated in T71L6816A include sixteen full-duplex media access
controller(MAC) with RMII interface to PHYs, one address resolution logic(ARL), one
flow control unit and one buffer management unit(BMU).
The T71L6816A supports IEEE 802.3x flow control in full-duplex mode and back-pressure
control in half-duplex mode. Also, the T71L6816A is fully compatible to the ability
for auto-negotiation with its link partner by periodically polling the status of PHYs.
The T71L6816A provides the port-based VLAN group function to help users to isolate traffic
segment by segment for the sake of security and bandwidth saving. Maximum three VLANs
can be divide by users and it is suitable for application in small office or home.
The T71L6816A also supports the port-based trunking applications. With trunking enabled,
it is possible to aggregate up to four full-duplex links to form a single channel with
400Mbit/s data rate and to provide the load sharing effect.
The T71L6816A will also support the QoS requirement for some networks. With QoS enabled
in networks which is compatible to VLAN QoS, the T71L6816A will put incoming packets into
different priority output queues by checking the QoS field in their VLAN header. If the
user’s network do not support VLAN QoS, the T71L6816A still offers an alternative way
