General Description The KS8001 is a 10BASE-T/100BASE-TX/FX Physical Layer Transceiver, operating the core at 1.8 volts to meet low voltage and low power requirements. The solution provides MII/RMII/SMII interfaces to transmit and receive data. A unique mixed-signal design extends signaling distance while reducing power consumption. HP Auto MDI/MDI-X provides the most robust solution for eliminating the need to differentiate between crossover and straight-through cables. Featuring LinkMD cable diagnostics, which allows detection of common cabling plant problems such as open and short circuits, the KS8001 represents a new level of features and performance and is an ideal choice of physical layer transceiver for 100BASE-TX/10BASE T/100BASE-FX applications. Features • Single chip 100BASE-TX/100BASE-FX/10BASE-T physical layer solution • 1.8V CMOS design, power consumption 250 mW • Robust (130m+) operation over standard cables • Supports Media Independent Interface (MII), Reduced MII (RMII), and Serial MII (SMII) • LinkMD feature to determine cable length and diagnose faulty cables up 200 m with +/- 2 m accuracy • Supports HP MDI/MDI-X auto crossover • Supports power down mode and power saving mode • MDC/MDIO to 12.5 MHz for rapid configuration • Fully compliant to IEEE 802.3u standard • Supports auto-negotiation and manual selection for 10/100Mbps speed and full / half-duplex mode • Configurable through MII serial management ports or via external control pins • Programmable LED outputs for link, activity, full/half duplex, collision and speed • On-chip built-in analog front end filtering for both 100BASE-TX and 10BASE-T • Supports back to back, FX to TX for media converter applications • Single 3.3V power supply with built-in 1.8V regulator (‘L’ parts) • 48 Pin LQFP, 48 Pin SSOP, 48 Pin QFN (targeted)
