KSZ8721SLI

The KSZ8721SLI is a 3.3V single power supply 10/100BASE-TX/FX MII Physical-Layer Transceiver, operating with a 2.5V core to meet low-voltage and low power requirements. The transceiver that use MII and RMII interfaces to transmit and receive data. It contains 10Base-T physical medium attachment (PMA), physical medium dependent (PMD) and physical coding sub-layer (PCS) functions. It also has on-chip 10BASE-T output filtering. This eliminates the need for an external filters and allows a single set of line magnetics to be used to meet requirements for both 100BASE-TX and 10BASE-T. It automatically configures itself for 100 or 10Mbps and full- or half-duplex operation, using an on-chip auto-negotiation algorithm.
