KS8721CL
3.3V Single Power Supply 10/100BASE-TX/FX MII Physical Layer Transceiver
Rev. 1.0
General Description
The KS8721CL 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 consump-
tion, the KS8721CL represents Micrel’s fourth generation
single-port Fast Ethernet PHY.
The KS8721CL contains 10BASE-T physical medium attach-
ment (PMA), physical medium dependent (PMD), and physi-
cal coding sub-layer (PCS) functions. It also has on-chip
10BASE-T output filtering. This eliminates the need for
external filters and allows a single set of line magnetics to be
used to meet requirements for both 100BASE-TX and
10BASE-T.
The KS8721CL automatically configures itself for 100Mbps
or 10Mbps and full- or half-duplex operation, using an on-chip
auto-negotiation algorithm. It is the ideal physical layer
transceiver for 100BASE-TX/10BASE-T applications.
