2 General Description Operating with a 2.
5V core to meet low-voltage and low-power requirements, the KS8721BL and KS8721SL are 10BASET/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 1...
