KSZ8021RNL / KSZ8031RNL  
10Base-T/100Base-TX PHY  
with RMII Support  
General Description  
Features  
The KSZ8031RNL is a single-supply 10Base-T/100Base-  
TX Ethernet physical layer transceiver for transmission  
and reception of data over standard CAT-5 unshielded  
twisted pair (UTP) cable.  
• Single-chip 10Base-T/100Base-TX IEEE 802.3  
compliant Ethernet Transceiver  
• RMII v1.2 Interface support with 50MHz reference clock  
output to MAC, and option to input 50MHz reference  
clock  
The KSZ8031RNL is a highly-integrated, compact solution.  
It reduces board cost and simplifies board layout by using  
on-chip termination resistors for the differential pairs, by  
integrating a low noise regulator to supply the 1.2V core,  
and by offering 1.8/2.5/3.3V digital I/O interface support.  
• RMII back-to-back mode support for 100Mbps copper  
repeater or media converter  
• MDC/MDIO Management Interface for PHY register  
configuration  
The KSZ8031RNL offers the Reduced Media Independent  
Interface (RMII) for direct connection to RMII-compliant  
MACs in Ethernet processors and switches.  
• Programmable interrupt output  
• LED outputs for link and activity status indication  
• On-chip termination resistors for the differential pairs  
• Baseline Wander Correction  
• HP Auto MDI/MDI-X for reliable detection and  
correction for straight-through and crossover cables  
with disable and enable option  
As the power-up default, the KSZ8031RNL uses a 25MHz  
crystal to generate all required clocks, including the  
50MHz RMII reference clock output for the MAC. The  
KSZ8021RNL is the version that takes in the 50MHz RMII  
reference clock as the power-up default.  
To facilitate system bring-up and debugging in production  
testing and in product deployment, parametric NAND tree  
support enables fault detection between KSZ8031RNL  
I/Os and board, while Micrel’s LinkMD® TDR-based cable  
diagnostics permit identification of faulty copper cabling.  
• Auto-negotiation to automatically select the highest link-  
up speed (10/100 Mbps) and duplex (half/full)  
• Power down and power saving modes  
• LinkMD® TDR-based cable diagnostics for identification  
of faulty copper cabling  
The KSZ8031RNL and KSZ8021RNL are available in 24-  
pin, lead-free QFN packages (see Ordering Information).  
• Parametric NAND Tree support for fault detection  
between chip I/Os and board
