    KSZ9021GN - Gigabit Ethernet Transceiver with GMII/MII Support
    Docket ↓
    KSZ9021GN
    Gigabit Ethernet Transceiver
    with GMII / MII Support General Description Features The KSZ9021GN is a completely integrated triple speed Single-chip 10/100/1000Mbps IEEE 802.3 compliant
    (10Base-T/100Base-TX/1000Base-T) Ethernet Physical
    Ethernet Transceiver
    Layer Transceiver for transmission and reception of data GMII/MII standard compliant interface
    on standard CAT-5 unshielded twisted pair (UTP) cable. Auto-negotiation to automatically select the highest link
    The KSZ9021GN provides the industry standard GMII/MII
    up speed (10/100/100Mbps) and duplex (half/full)
    (Gigabit Media Independent Interface / Media Independent On-chip termination resistors for the differential pairs
    Interface) for connection to GMII/MII MACs in Gigabit On-chip LDO controller to support single 3.3V supply
    Ethernet Processors and Switches for data transfer at
    operation – requires only external FET to generate 1.2V
    1000 Mbps or 10/100Mbps speed.
    for the core
    The KSZ9021GN reduces board cost and simplifies board Jumbo frame support up to 16KB
    layout by using on-chip termination resistors for the four 125MHz Reference Clock Output
    differential pairs and by integrating a LDO controller to
    drive a low cost MOSFET to supply the 1.2V core. Programmable LED outputs for link, activity and speed
    The KSZ9021GN provides diagnostic features to facilitate Baseline Wander Correction
    В®
    system bring-up and debugging in production testing and LinkMD TDR-based cable diagnostics for identification
    in product deployment. Parametric NAND tree support ...

    KSZ9021RL/RN - Gigabit Ethernet Transceiver with RGMII Support
    Docket ↓
    KSZ9021RL/RN
    Gigabit Ethernet Transceiver
    with RGMII Support
    Revision 1.2 General Description Features The KSZ9021RL is a completely integrated triple speed
    (10Base-T/100Base-TX/1000Base-T) Ethernet Physical
    Layer Transceiver for transmission and reception of data
    over standard CAT-5 unshielded twisted pair (UTP) cable.
    The KSZ9021RL provides the Reduced Gigabit Media
    Independent Interface (RGMII) for direct connection to
    RGMII MACs in Gigabit Ethernet Processors and Switches
    for data transfer at 10/100/1000Mbps speed.
    The KSZ9021RL reduces board cost and simplifies board
    layout by using on-chip termination resistors for the four
    differential pairs and by integrating a LDO controller to
    drive a low cost MOSFET to supply the 1.2V core.
    The KSZ9021RL provides diagnostic features to facilitate
    system bring-up and debugging in production testing and
    in product deployment. Parametric NAND tree support
    enables fault detection between KSZ9021 I/Os and board.
    В®
    Micrel LinkMD TDR-based cable diagnostics permit
    identification of faulty copper cabling. Remote and local
    loopback functions provide verification of analog and ...
