Microchip | KSZ8842-16MQL

Micrel Inc., is a leading manufacturer of IC solutions for the worldwide analog, Ethernet and high bandwidth markets. The Company's products include high performance analog, power, advanced mixed-signal and radio frequency semiconductors; high-speed communication, clock management, Ethernet switch and physical layer transceiver integrated circuits. These products address a wide range of rapidly growing end markets including cellular handsets, portable and enterprise computing, enterprise and home networking, wide area and metropolitan area networks and industrial equipment.

Micrel acquired Kendin Communications in June of 2001. The Ethernet product line has continued to evolve and grow with the market. Micrel's Controllers are known for robust performance, interoperability and low power.

The KSZ8842-16MQL and KSZ8842-32MQL are the industry’s first 2-port switches with a non-PCI CPU interface. The KSZ8842-16MQL (or –32MQL) is a proven, 4th generation, integrated, Layer 2 switch that is compliant to the IEEE802.3u standard.

The KSZ8842-16MQL (or –32MQL) 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 in the repeater mode, the KSZ8842-16MQL (or –32MQL) runs in half-duplex mode regardless if the application.

The KSZ8842-16MQL (or –32MQL) 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 KSZ8842-16MQL (or -32MQL) 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 on-chip frame buffer memory.

The KSZ8842-16MQL is a controller with a 2 Ethernet ports. It has a supply voltage of 3.3V and is packaged as a 128-PQFP. The KSZ8842-16MQL is housed in a tray.
