This datasheet also covers the KSZ9021RN variant, as both devices belong to the same gigabit ethernet transceiver family and are provided as variant models within a single manufacturer datasheet.
General Description
The KSZ9021RL is a completely integrated triple speed (10Base-T/100Base-TX/1000Base-T) Ethernet Physical Layer Transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable.
Key Features
to facilitate system bring-up and debugging in production testing and in product deployment. Parametric NAND tree support enables fault detection between KSZ9021 I/Os and board. Micrel LinkMD® TDR-based cable diagnostic.
Note: The manufacturer provides a single datasheet file (KSZ9021RN-MicrelSemiconductor.pdf) that lists specifications for multiple related part numbers.

Z9021RL is a completely integrated triple speed (10Base-T/100Base-TX/1000Base-T) Ethernet Physical Layer Transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable. The KSZ9021RL provides the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to RGMII MACs in Gigabit Ethernet Processors and Switches for data transfer at 10/100/1000Mbps speed. The KSZ9021RL reduces board cost and simplifies board layout by using on-chip termination resistors for the four differential pairs and by integrating a LDO controller to drive a low cost MOSFET to supply the 1.2V
