FIFO, Flow Control, VLAN Tagging ,Priority KSZ8862-16/32MQL 2-Port Ethernet Switch with Non-PCI Interface and Fiber Support Rev 3.1 General Description The KSZ8862M is 2-port switch with non-PCI CPU interface and fiber support, and is available in 8/16-bit LinkMD and 32-bit bus designs (see Ordering Information). This datasheet describes the KSZ8862M non-PCI CPU In copper mode, port 2 supports 10/100BASE-T/TX with interface chip. HP Auto MDI/MDI-X for reliable detection of and The KSZ8862M is the industrys first fully managed, 2- correction for straight-through and crossover cables. port switch with a non-PCI CPU interface and fiber Micrels proprietary LinkMD Time Domain th support. It is based on a proven, 4 generation, Reflectometry (TDR)-based function is also available for integrated Layer-2 switch, compliant with IEEE 802.3u determining the cable length, as well as cable standards. diagnostics for identifying faulty cabling. For industrial applications, the KSZ8862M can run in The KSZ8862M offers an extensive feature set that half-duplex mode regardless of the application. includes tag/port-based VLAN, quality of service (QoS) priority management, management information base In fiber mode, port 1 can be configurable to either (MIB) counters, and CPU control/data interfaces to 100BASE-FX or 100BASE-SX/10BASE-FL. effectively address Fast Ethernet applications. The LED driver and post amplifier are also included for The KSZ8862M contains: Two 10/100 transceivers with 10Base-FL and 100Base-SX applications. patented, mixed-signal, low-power technology, two media access control (MAC) units, a direct memory access (DMA) channel, a high-speed, non-blocking, switch fabric, a dedicated 1K entry forwarding table, and an on-chip frame buffer memory.
