XTS-0812, Layer 2 Managed 8 + 2 Port 10/100/1000 Switch Controller

XTS-0812 is a LQFP176 E-PAD, high-performance 8+2-port Gigabit Ethernet switch. It integrates eight PHY ports support 1000Base-T/100Base-TX/10Base-Te,two extra MAC ports for specific applications which supports 2500BX/SGMII/1000Base-X/100Base-FX/RGMII/MII/RMII. XTS-0812 is also embedded with a RISC-V microprocessor. The integrated Giga-PHY complies with 10Base-Te, 100Base-TX, and 1000Base-T IEEE standard 802.3 and also support Xtramus proprietary LRE100-4 feature, which makes the device can auto-negotiate and link up with LRE100-4 compliant link partners, in extended cable length applications up to 400 meters at 100Mbps over CAT5E cable. The Extension GMAC1 and Extension GMAC2 of the XTS-0812 supports xMII or SerDes connecting with an external PHY, MAC, external CPU or RISC in specific applications. The xMII refer to Reduced Gigabit Media Independent Interface (RGMII), Media Independent Interface (MII), and Reduced Media Independent Interface (RMII). The SerDes supports IEEE 100Base-FX, IEEE 1000Base-X and IEEE 2500Base-X. XTS-0812 integrates a 4K look-up table with an efficient hashing algorithm for address searching and learning, each entry also can be configured as a static entry. XTS-0812 supports IEEE 802.1Q VLAN and has a 4K-entry VLAN table. It provides VLAN classification according to port-based, protocol -based, VLAN translation, Flow-based capability?and MAC-based, IP-subnet-based VLAN can be supported by configuration It also supports IVL, SVL, and IVL/SVL for flexible network topology architecture. The XTS-0812 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. The XTS-0812 supports storm control. In order to support flexible traffic classification, the XTS-0812 supports 383-hardware entry ACL rules check and multiple actions options. The 383 entries are composed of 48 rows, each row has 8 entries. To support long rule, rule extension is supported by any combinations of the 8 entries for each row. 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. The ACL action can be configured as Drop/Permit/Redirect/ Mirror, change priority/DSCP value in 802.1q, and rate policing when an ACL rule matches.
