Description
The KS8721BL/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 KS8721BL/SL 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
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 auto-
matic detection of cable energy.

3.3V 10/100BASE-TX/FX Physical Layer Transceiver
The KS8721BL/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 detec-
tion of crossover and straight-through cables, the
KS8721BL/SL provides an easy-to-use, high performance
solution for 10BASE-T, 100BASE-TX, and 100BASE-FX
applications.
