Revision 1.2
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.
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 core.
The KSZ9021RL 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.
The KSZ9021RL is available in a 64-pin, lead-free E-LQFP
package, and is offered as the KSZ9021RN in the smaller
48-pin QFN package (See Ordering Information).
Features
Single-chip 10/100/1000Mbps IEEE 802.3 compliant
Ethernet Transceiver
RGMII interface compliant to RGMII Version 1.3
RGMII I/Os with 3.3V/2.5V tolerant and programmable
timings to adjust and correct delays on both Tx and Rx
paths
Auto-negotiation to automatically select the highest link
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
Jumbo frame support up to 16KB
125MHz Reference Clock Output
Programmable LED outputs for link, activity and speed
Baseline Wander Correction
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
