Product Summary

The KS8721BL is a Single Power Supply Physical Layer Transceiver. Operating with a 2.5V core to meet low-voltage and low-power requirements, the KS8721BL uses MII and RMII interfacesto transmit and receive data. The device contains 10BASE-T Physical Medium Attachment (PMA), PhysicalMedium Dependent (PMD), and Physical Coding Sub-layer (PCS) functions. The KS8721BL 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.
