General Description
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.
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.
Features
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
Supports power-down and power-saving modes
Congurable through MII serial management ports or
via external control pins
