KS8001Product Brief www.micrel.com 1.8V, 3.3V 10/100BASE-TX/FX Physical Layer Transceiver Description The KS8001 is a 10BASE-T,100BASE-TX, and 100BASEFX Physical Layer Transceiver, which provides MII/RMII/ SMII interfaces to MACs and switches. Utilizing a unique mixed-signal design that extends signaling distance while reducing power consumption, the KS8001 represents Micrel's fifth generation single-port Fast Ethernet PHY. Micrel's architecture, when run at a core voltage of 1.8V, allows the KS8001 to dissipate an ultra-low 250mW in power. This translates to increased reliability while enabling deployment in today's power-sensitive applications. Multiple power-down modes, accessed via configuration pins or registers, allow further levels of power saving through manual selection or automatic detection of cable energy. LinkMDTM cable diagnostics, an industry first for singleport Fast Ethernet PHYs, detects common cabling plant problems such as open and short circuits. Diagnosis and elimination of cabling faults can lead to reduced user frustration and fewer equipment returns, both in enterprise and consumer electronics applications. Combined with HP Auto-MDIX, deployment is dramatically simplified by providing the most robust solution for automatically adjusting to crossover and straight-through cables. The KS8001 represents a new level of features and performance, and is an ideal choice of physical layer transceiver for 10BASE-T, 100BASE-TX, and 100BASEFX applications.
