KSZ9021GN  
Gigabit Ethernet Transceiver  
with GMII / MII Support  
General Description  
Features  
The KSZ9021GN is a completely integrated triple speed  
(10Base-T/100Base-TX/1000Base-T) Ethernet Physical  
Layer Transceiver for transmission and reception of data  
on standard CAT-5 unshielded twisted pair (UTP) cable.  
• Single-chip 10/100/1000Mbps IEEE 802.3 compliant  
Ethernet Transceiver  
• GMII/MII standard compliant interface  
• Auto-negotiation to automatically select the highest link  
The KSZ9021GN provides the industry standard GMII/MII  
(Gigabit Media Independent Interface / Media Independent  
Interface) for connection to GMII/MII MACs in Gigabit  
Ethernet Processors and Switches for data transfer at  
1000 Mbps or 10/100Mbps speed.  
up speed (10/100/100Mbps) and duplex (half/full)  
• On-chip termination resistors for the differential pairs  
• On-chip LDO controller to support single 3.3V supply  
operation – requires only external FET to generate 1.2V  
for the core  
The KSZ9021GN 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 core.  
• Jumbo frame support up to 16KB  
• 125MHz Reference Clock Output  
• Programmable LED outputs for link, activity and speed  
• Baseline Wander Correction  
The KSZ9021GN provides diagnostic 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 diagnostics permit  
identification of faulty copper cabling. Remote and local  
loopback functions provide verification of analog and  
digital data paths.  
• LinkMD® TDR-based cable diagnostics for identification  
of faulty copper cabling  
• Parametric NAND Tree support for fault detection  
between chip I/Os and board.  
• Loopback modes for diagnostics  
• Automatic MDI/MDI-X crossover for detection and  
correction of pair swap at all speeds of operation  
The KSZ9021GN is available in a 64-pin, lead-free QFN  
package (See Ordering Information).
