Download the KSZ8721BL datasheet PDF.
This datasheet also covers the KSZ8721SL variant, as both devices belong to the same 3.3v single power supply 10/100base-tx/fx mii physical layer transceiver family and are provided as variant models within a single manufacturer datasheet.
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.
Key Features
Single chip 100BASE-TX/100BASE-FX/10BASE-T physical layer solution.
2.5V CMOS design; 2.5/3.3V tolerance on I/O.
3.3V single power supply with built-in voltage regulator; Power consumption.
Note: The manufacturer provides a single datasheet file (KSZ8721SL_MicrelSemiconductor.pdf) that lists specifications for multiple related part numbers.

ver www.DataSheet4U.com Rev. 1.2 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 100BASE-TX and 10BASE-T.
