Description The KSZ8842-PMQL is the industry’s first 2-port switch with a PCI CPU interface. An Industrial Temperature grade part, the KSZ8842-PMQLI will also available from Q1, 2006. The KSZ8842P is a proven, 4th generation, integrated, fully managed Layer 2 switch that is entirely compliant to IEEE802.3u standards. The KSZ8842P can be configured as a low-latency repeater to allow for ‘cut thru’ in latency critical Embedded or Industrial Ethernet applications. For industrial automation applications, it runs in half-duplex mode. The KSZ8842P offers an extensive feature set that includes tag/port-based VLAN, QoS priority management, MAC filtering function, MIB counters, and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications. The KSZ8842P contains two 10/100 transceivers with patented mixed-signal low-power technology, two 1K entry media access control (MAC) units, a separate DMA channel, a high-speed non-blocking switch fabric, a dedicated 1K entry forwarding table, and an on-chip frame buffer memory.
