KS8721BL/SL  
3.3V Single Power Supply 10/100BASE-TX/FX  
MII Physical Layer Transceiver  
Rev. 1.3  
General Description  
Features  
Operating with a 2.5V core to meet low-voltage and low-  
power requirements, the KS8721BL and KS8721SL are  
10BASE-T/100BASE-TX/FX Physical Layer Transceivers  
that use MII and RMII interfaces to transmit and receive  
data. They contain 10BASE-T Physical Medium  
Attachment (PMA), Physical Medium Dependent (PMD),  
and Physical Coding Sub-layer (PCS) functions. The  
KS8721BL/SL also have on-chip 10BASE-T output  
ltering. This eliminates the need for external lters and  
allows a single set of line magnetics to be used to meet  
requirements for both 100BASE-TX and 10BASE-T.  
Single chip 100BASE-TX/100BASE-FX/10BASE-T  
physical layer solution  
2.5V CMOS design; 2.5/3.3V tolerance on I/O  
3.3V single power supply with built-in voltage  
regulator; Power consumption <340mW (including  
output driver current)  
Fully compliant to IEEE 802.3u standard  
Supports MII and Reduced MII (RMII)  
Supports 10BASE-T, 100BASE-TX, and 100BASE-FX  
with Far_End_Fault Detection  
The KS8721BL/SL automatically configure themselves  
for 100 or 10Mbps and full- or half-duplex operation,  
using an on-chip auto-negotiation algorithm. They are the  
ideal physical layer transceiver for 100BASE-TX/  
10BASE-T applications.  
Supports power-down and power-saving modes  
Congurable through MII serial management ports or  
via external control pins
