Features & Applications

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 KSZ8721BL/SL is a 10BASE-T, 100BASE-TX, and 100BASE-FX 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 KSZ8721BL/SL represents Micrel’s fourth generation single-port Fast Ethernet PHY.

Micrel’s architecture dissipates an ultra-low 275mW in power, including transmit output drivers. This translates to increased reliability while enabling deployment in today’s power-sensitive applications. Multiple power-down modes, accessed vas configuration pins or registers, allow further levels of power-saving through manual selection or automatic detection of cable energy.

The KSZ8721BL/SL automatically configures itself for 100Mbps or 10Mbps and full- or half-duplex operation, using an on-chip auto-negotiation algorithm. Combined with Auto MDI/MDIX for automatic correction and detection of crossover and straight-through cables, the KSZ8721BL/SL provides an easy-to-use, high performance solution for 10BASE-T, 100BASE-TX, and 100BASE-FX applications.

The KSZ8721BL TR is a Physical Layer Transceiver with a supply voltage of 3.3V. It is packaged as a 48-LQFP. The KSZ8721BL TR comes in tape and reel format.
