KSZ8721BL Datasheet PDF - Microchip

The KSZ8721BL is a single power supply 10/100BASE-TX/FX MII Physical-layer Transceiver, contains 10BASE-T Physical medium attachment (PMA), physical medium dependent (PMD) and physical coding sub-layer (PCS) functions. It also have on-chip 10BASE-T output filtering. This eliminates the need for external filters and allows a single set of line magnetic to be used to meet requirements for both 100BASE-TX and 10BASE-T. It is automatically configure themselves for 100 or 10Mbps and full- or half-duplex operation, using an on-chip auto-negotiation algorithm. The physical layer transceiver is ideal for 100BASE-TX/10BASE-T applications.
