Realtek RTL8306SD-VC-GR
The RTL8306SD/RTL8306SDM is a 6-port Fast Ethernet switch controller that integrates memory, six MACs, and five physical layer transceivers for 10Base-T and 100Base-TX operation into a single chip. The RTL8306SD/RTL8306SDM support a Dual MII/RMII interface for external devices to connect to the 6th MAC, 5th MAC, and 5th PHY. The external device could be a routing engine, HomePNA, HomePlug, or VDSL transceiver depending on the application.GENERAL DESCRIPTION
In order to accomplish diagnostics in complex network systems, the RTL8306SD/RTL8306SDM provides a loopback feature in each port. The RTL8306SD/RTL8306SDM supports several advanced QoS functions with four-level priority queues to improve multimedia or real-time networking applications, including:● Multi priority assignment
● Differential queue weight
● Port-based and queue-based rate limitation
● 16-entry ACL for advanced packet control application Note: RTL8306SD and RTL8306SDM difference is that the ACL (Access Control List) function is supported only by the RTL8306SDM (see 8.1 ACL Function, page 52). For multicast applications, the RTL8306SD/RTL8306SDM supports IGMPv1/v2/v3 and MLDv1/v2 snooping. To meet security and management requirements, the RTL8306SD/RTL8306SDM supports IEEE 802.1x Port-based/MAC-based Access Control, provides a Port Mirroring function, and also supports five 32-bit MIB Counters on each port. The RTL8306SD/RTL8306SDM supports 16 VLAN groups.
