RTL8304MB-CG
Overview
The RTL8304MB-CG is a 4-port 10/100M Ethernet switch controller that integrates memory, four MACs, and three physical layer transceivers for 10Base-T and 100Base-TX operation into a single chip. It supports an RMII interface for external devices to connect to the 4th MAC.
- Multi-priority assignment
- Differential queue weight
- Port-based rate limitation
- Queue-based rate limitation The RTL8304MB supports 16 VLAN groups. These can be configured as port-based VLANs and/or 802.1Q tag-based VLANs. The RTL8304MB also supports VLAN learning, with four Independent VLAN Learning (IVL) filtering databases. The RTL8304MB contains a 2K-entry address lookup table. A 4-way associative hash algorithm avoids hash collisions and maintains forwarding performance. Maximum packet length can be 2048 bytes. Three types of independent storm filter are provided to filter packet storms, and an intelligent switch engine prevents Head-of-Line blocking problems. The RTL8304MB supports Energy-Efficient Ethernet mode (EEE; defined in IEEE 802.3az) to minimize system power consumption. Energy-Efficient Ethernet supports Low Power Idle Mode. When Low Power Idle Mode is enabled, systems on both sides of the link can disable portions of the funct
