KSZ8842-16MVIL

KSZ8842-16/32 MQL/MVL/MVLI/MBL 2-Port Ethernet Switch with Non-PCI Interface Data Sheet Rev 1.9 General Description The KSZ8842-series of 2-port switches includes PCI and non-PCI CPU interfaces, and are available in 8/16-bit and 32-bit bus designs (see Ordering Information). This datasheet describes the KSZ8842M-series of nonPCI CPU interface chips. For information on the KSZ8842 PCI CPU interface switches, refer to the KSZ8842P datasheet. The KSZ8842M is the industry’s first fully managed, 2port switch with a non-PCI CPU interface. It is based on th a proven, 4 generation, integrated Layer-2 switch, compliant with IEEE 802.3u standards. Also an industrial temperature grade version of the KSZ8842, the KSZ8842MVLI, can be ordered (see Ordering Information). The KSZ8842M can be configured as a switch or as a low-latency (≤ 310 nanoseconds) repeater in latencycritical, embedded or industrial Ethernet applications. For industrial applications, the KSZ8842M can run in half-duplex mode regardless of the application. LinkMD ® The KSZ8842M offers an extensive feature set that includes tag/port-based VLAN, quality of service (QoS) priority management, management information base (MIB) counters, and CPU control/data interfaces to effectively address Fast Ethernet applications. The KSZ8842M 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...
