    KSZ8721B-BT Data Sheet
    Docket ↓
    KS8721B/BT
    2.5V 10/100BasTX/FX MII Physical Layer Transceiver Rev. 2.3 General Description Features Operating at 2.5 volts to meet low voltage and low power
    requirements, the KS8721B/BT is a 10BaseT/100BaseTX/FX
    Physical Layer Transceiver, which provides an MII to transmit
    and receive data. It contains the 10BaseT Physical Medium
    Attachment (PMA), Physical Medium Dependent (PMD), and
    Physical Coding Sub-layer (PCS) functions. Moreover, the
    KS8721B/BT has on-chip 10BaseT output filtering, which
    eliminates the need for external filters and allows a single
    set of line magnetics to be used to meet requirements for
    both 100BaseTX and 10BaseT.
    The KS8721B/BT can automatically configure itself for 100
    or 10 Mbps and full or half duplex operation, using on-chip
    Auto-Negotiation algorithm. It is an ideal choice of physical
    layer transceiver for 100BaseTX/10BaseT applications.

    Docket ↓
    KS8721BL/SL
    3.3V Single Power Supply 10/100BASE-TX/FX
    MII Physical Layer Transceiver
    Rev. 1.3 General Description Features Operating with a 2.5V core to meet low-voltage and lowpower requirements, the KS8721BL and KS8721SL are
    10BASE-T/100BASE-TX/FX Physical Layer Transceivers
    that use MII and RMII interfaces to transmit and receive
    data. They contain 10BASE-T Physical Medium
    Attachment (PMA), Physical Medium Dependent (PMD),
    and Physical Coding Sub-layer (PCS) functions. The
    KS8721BL/SL also have on-chip 10BASE-T output
    filtering. This eliminates the need for external filters and
    allows a single set of line magnetics to be used to meet
    requirements for both 100BASE-TX and 10BASE-T.
    The KS8721BL/SL automatically configure themselves
    for 100 or 10Mbps and full-or half-duplex operation,
    using an on-chip auto-negotiation algorithm. They are the
    ideal physical layer transceiver for 100BASE-TX/
    10BASE-T applications. Single chip 100BASE-TX/100BASE-FX/10BASE-T
    physical layer solution 2.5V CMOS design; 2.5/3.3V tolerance on I/O 3.3V single power supply with built-in voltage

    Docket ↓
    KS8721CL Micrel, Inc. KS8721CL
    3.3V Single Power Supply 10/100BASE-TX/FX MII Physical Layer Transceiver Rev. 1.2 General Description Features The KS8721CL is a 10BASE-T, 100BASE-TX, and 100BASEFX physical layer transceiver providing MII/RMII interfaces to
    MACs and switches. Using a unique mixed-signal design that
    extends signaling distance while reducing power consumption, the KS8721CL represents Micrel’s fourth generation
    single-port Fast Ethernet PHY.
    The KS8721CL contains 10BASE-T physical medium attachment (PMA), physical medium dependent (PMD), and physical coding sub-layer (PCS) functions. It also has on-chip
    10BASE-T output filtering. This eliminates the need for
    external filters and allows a single set of line magnetics to be
    used to meet requirements for both 100BASE-TX and
    10BASE-T.
    The KS8721CL automatically configures itself for 100Mbps
    or 10Mbps and full-or half-duplex operation, using an on-chip
    auto-negotiation algorithm. It is the ideal physical layer
    transceiver for 100BASE-TX/10BASE-T applications. Single chip 100BASE-TX/100BASE-FX/10BASE-T
