ИС, Ethernet KSZ8842-PMQLI

Ethernet контроллер , 100 Мбит/с, IEEE 802.3u, 3.1 В, 3.5 В, QFP, 128 вывод(-ов)

The KSZ8842-PMQLI is a 2-port fully managed Ethernet Switch with a 32-bit/33MHz PCI processor interface. It is a proven, 4th generation, integrated Layer 2 switch that is compliant with the IEEE 802.3u standard. It can be configured as a switch or as a low-latency (<310 nanoseconds) repeater in latency-critical, embedded or industrial Ethernet applications. For industrial automation applications. can run in half-duplex mode regardless of the application. It offers an extensive feature set that includes tag/portbased VLAN, quality of service (QoS) priority management, management information base (MIB) counters and CPU control/data interfaces to effectively address Fast Ethernet applications. It contains two 10/100 transceivers with patented, mixed-signal, low-power technology three 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.
