The RTL8365MB-CG is an LQFP128, high-performance 4+1-port Gigabit Ethernet switch featuring low?power integrated Quad-port Giga-PHYs that support 1000Base-T, 100Base-TX, and 10Base-T. For specific applications, the RTL8365MB supports an extra interface that could be configured as a GMII/RGMII/MII interface. The RTL8365MB integrates all the functions of a high-speed switch system; including SRAM for packet buffering, non-blocking switch fabric, and internal register management into a single CMOS device. Only a 25MHz crystal is required; an optional EEPROM is offered for internal register configuration. The embedded packet storage SRAM in the RTL8365MB features superior memory management technology to efficiently utilize memory space. The RTL8365MB integrates a 2K-entry look-up table with a 4-way XOR Hashing algorithm for address searching and learning. The table provides read/write access from the EEPROM Serial Management Interface (SMI), Media Independent Interface Management (MIIM), or SPI Interface. Each of the entries can be configured as a static entry. The entry aging time is between 200 and 400 seconds. Eight Filtering Databases are used to provide Independent VLAN Learning and Shared VLAN Learning (IVL/SVL) functions. The Extension GMAC1 of the RTL8365MB implements a GMII/RGMII/MII interface. The interface could be connected to an external PHY, MAC, CPU, or RISC for specific applications. In router applications, the RTL8365MB supports Port VID (PVID) for each port to insert a PVID in the VLAN tag on egress. When using this function, VID information carried in the VLAN tag will be changed to PVID. Note: The RTL8365MB Extra Interface (Extension GMAC1) supports: Dual-Port Gigabit Media Independent Interface (GMII) Dual-Port Reduced Gigabit Media Independent Interface (RGMII) Dual-Port Media Independent Interface (MII) The RTL8365MB supports standard 802.3x flow control frames for full duplex, and optional backpressure for half duplex. It determines when to invoke the flow control mechanism by checking the availability of system resources, including the packet buffers and transmitting queues. The RTL8365MB supports broadcast/multicast output dropping, and will forward broadcast/multicast packets to non-blocked ports only. For IP multicast applications, the RTL8365MB supports IPv4 IGMPv1/v2/v3 and IPv6 MLDv1/v2 snooping. In order to support flexible traffic classification, the RTL8365MB supports 64-entry ACL rule check and multiple actions options. Each port can optionally enable or disable the ACL rule check function. The ACL rule key can be based on packet physical port, Layer2, Layer3, and Layer4 information. When an ACL rule matches, the action taken is configurable to Drop/Permit/Redirect/Mirror, change priority value in 802.1q/Q tag, and rate policing. The rate policing mechanism supports from 8Kbps to 1Gbps (in 8Kbps steps).
