Micrel KSZ8842-16MQL-EVAL

接口以太网控制器（PHY 和 MAC）板

Overview

The KSZ8842-series of 2-port switches includes PCI and non-PCI CPU interfaces. The datasheet describes the KSZ8842-PMQL/PMBL PCI CPU interface chips. KSZ8842-PMQL is PQFP package chip, KSZ8842-PMBL is LFBGA package chip. For information on the KSZ8842-MQL/MBL CPU non-PCI interface switches, refer to the KSZ8842-MQL/MBL datasheet.The KSZ8842-PMQL/PMBL is the industry's first fully managed 2-port 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. An industrial temperature grade version of the KSZ8842-PMQL/PMBL, also can be ordered the KSZ8842-PMQLI/PMBL AM.The KSZ8842-PMQL/PMBL 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, theKSZ8842-PMQL/PMBL can run in half-duplex mode regardless of the application. The KSZ8842-PMQL/PMBL 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 KSZ8842-PMQL/PMBL 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.Microchip's complimentary and confidential LANCheck® online design review service is available for customers who have selected our products for their application design-in. The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
