Physical Layer Transceiver
DATASHEET V 1.01
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
