KSZ8862-16MQL Datasheet | Micrel Semiconductor

Description The KSZ8862M is 2-port switch with non-PCI CPU interface and fiber support, and is available in 8/16-bit and 32-bit bus designs (see Ordering Information). This datasheet describes the KSZ8862M non-PCI CPU interface chip. The KSZ8862M is the industry’s first fully managed, 2port switch with a non-PCI CPU interface and fiber th support. It is based on a proven, 4 generation, integrated Layer-2 switch, pliant with IEEE 802.3u standards. For industrial applications, the KSZ8862M can run in half-duplex mode regardless of the application. In fiber mode, port 1 can be configurable to either 100BASE-FX or 100BASE-SX/10BASE-FL. The LED driver and post amplifier are also included for 10Base-FL and 100Base-SX applications. Link MD ® In copper mode, port 2 supports 10/100BASE-T/TX with HP Auto MDI/MDI-X for reliable detection of and correction for straight-through and crossover cables. ® Micrel’s proprietary Link MD Time Domain Reflectometry (TDR)-based function is also available for determining the cable length, as well as cable diagnostics for identifying faulty cabling. The KSZ8862M offers an extensive feature set that includes tag/port-based VLAN, quality of service (Qo S) priority management, management information base (MIB) counters, and CPU control/data interfaces to effectively address Fast Ethernet applications. The KSZ8862M contains: Two 10/100 transceivers with 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.
