The KSZ8041NL is a single supply 10Base-T/100Base-TX Physical Layer Transceiver, which provides MII/RMII interfaces to transmit and receive data. A unique mixed signal design extends signaling distance while reducing power consumption.

HP Auto MDI/MDI-X provides the most robust solution for eliminating the need to differentiate between crossover and straight-through cables.

The KSZ8041NL represents a new level of features and performance and is an ideal choice of physical layer transceiver for 10Base-T/100Base-TX applications.

The KSZ8041NL comes in a 32-pin, lead-free MLF® (QFN per JDEC) package (See Ordering Information).

    The KSZ8842-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.

    The KSZ8842-PMBL can be configured as a switch or as a low-latency (‹310 nanoseconds) repeater in latency-critical, embedded or industrial Ethernet applications. The KSZ8842-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-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.

    In addition to offering all of the features of an integrated Layer-2 managed switch, the KSZ8842-PMBL offers:

    • Repeater mode capabilities to allow for cut through in latency critical Industrial Ethernet or Embedded Ethernet applications
    • Dynamic buffer memory scheme essential for applications such as Video over IP where image jitter is unacceptable
    • 2-Port switch with a 32-bit/33MHz PCI processor interface
    • Micrel LinkMD® cable diagnostics to determine cable length, diagnose faulty cables, and determine distance-to-fault
    • Hewlett Packard (HP) Auto MDI-X crossover with disable and enable options
    • Four priority queues to handle voice, video, data, and control packets
    • Ability to transmit and receive jumbo frame sizes up to 1,916 bytes
