Micrel KS8721B
the KS8721B/BT is a 10BaseT/100BaseTX/FX Physical Layer Transceiver, which provides an MII to transmit and receive data. It contains the 10BaseT Physical Medium Attachment (PMA), Physical Medium Dependent (PMD), and Physical Coding Sub-layer (PCS) functions. The KS8721B/BT can automatically configure itself for 100 or 10 Mbps and full or half duplex operation, using on-chip Auto-Negotiation algorithm.| Part No. | KS8721B |

GENERAL DESCRIPTION
Operating at 2.5 volts to meet low voltage and low power requirements, Moreover, the KS8721B/BT has on-chip 10BaseT output filtering, which eliminates the need for external filters and allows a single set of line magnetics to be used to meet requirements for both 100BaseTX and 10BaseT. It is an ideal choice of physical layer transceiver for 100BaseTX/10BaseT applications. Data sheets and support documentation can be found on Micrel’s web site atFEATURES
