KS8721BL/SL
3.3V Single Power Supply 10/100BASE-TX/FX MII Physical Layer Transceiver
Rev. 1.1
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 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 configures itself for 100 or
10Mbps and full- or half-duplex operation, using an on-chip
auto-negotiation algorithm. It is the ideal physical layer
transceiver for 100BASE-TX/10BASE-T applications.
