KS8721B/BT
2.5V 10/100BasTX/FX MII Physical Layer Transceiver
Rev. 2.3
General Description
Operating at 2.5 volts to meet low voltage and low power
requirements,theKS8721B/BTisa10BaseT/100BaseTX/FX
Physical Layer Transceiver, which provides an MII to transmit
and receive data. It contains the 10BaseT Physical Medium
Attachment (PMA), Physical Medium Dependent (PMD), and
Physical Coding Sub-layer (PCS) functions. Moreover, the
KS8721B/BT has on-chip 10BaseT output ltering, which
eliminates the need for external lters and allows a single
set of line magnetics to be used to meet requirements for
both 100BaseTX and 10BaseT.
The KS8721B/BT can automatically congure itself for 100
or 10 Mbps and full or half duplex operation, using on-chip
Auto-Negotiation algorithm. It is an ideal choice of physical
layer transceiver for 100BaseTX/10BaseT applications.
Data sheets and support documentation can be found on
Micrel’s web site at www.micrel.com.
