General Description
Operating at 2.5 volts to meet low voltage and low power requirements, 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. Moreover, the KS8721B/BT has on-chip 10BaseT output fi ltering, which eliminates the need for external fi lters and allows a single set of line magnetics to be used to meet requirements for both 100BaseTX and 10BaseT.
Features
