Description

The KS8721BL 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  onsumption, the KS8721BL repre-sents 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  ncreased reliability while enabling deployment in today's power-sensitive applications. Multiple power-down modes,  ccessed via configuration pins or registers, allow further levels of power saving through manual selection or auto- atic detection of cable energy.

The KS8721BL automatically configures itself for 100Mbps or 10Mbps and full- or half-duplex operation, using an on- hip auto-negotiation algorithm. Combined with Auto MDI/MDIX for automatic correction and detec-tion of crossovernd straight-through cables, the KS8721BLprovides an easy-to-use, high performance solution for 10BASE-T,  00BASE-TX, and 100BASE-FX applications.
