Product Summary

Operating with a 2.5V core to meet low-voltage and lowpower
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.
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.
