Features & Applications

The KSZ9021RN is a 3.465 V ,10/100/100Mbps Gigabit Ethernet Transceiver with RGMII Support and its available in QFN-48 package .

The KSZ9021RL is a completely integrated triple speed Ethernet Physical Layer Transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable .

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.

Product 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
