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

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.

• 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

• Conﬁgurable through MII serial management ports or

via external control pins
