KSZ9021RN General Description

The KSZ9021RN is a cutting-edge Ethernet physical layer transceiver designed to meet the demanding requirements of automotive and industrial applications that rely on high-speed Ethernet connectivity. Its support for 10/100/1000 Mbps speeds ensures fast and reliable data transmission, while its low power consumption makes it an ideal choice for energy-sensitive environments. The inclusion of advanced power management features such as Energy Efficient Ethernet and Wake-On-LAN further enhances its efficiency, making it a sustainable option for businesses focused on reducing their energy footprint

Key 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
Automatic MDI/MDI-X crossover for detection and correction of pair swap at all speeds of operation
Automatic detection and correction of pair swap, pair skew and pair polarity
MDC/MDIO Management Interface for PHY register configuration
Interrupt pin option
Power down and power saving modes
Operating Voltages
Core: 1.2V (external FET or regulator)
I/O: 3.3V or 2.5V
Transceiver: 3.3V
Available packages
64-pin E-LQFP (10mm x 10mm): KSZ9021RL

The order reached the ryazan region in a month. It's okay. Ordered paid shipping from avaq standard shipping with tracking. It's more reliable. Especially order from 11 items. The seller collected and sent it pretty quickly. In general, a good store, the range is huge, found everything you need and some details only here. The price is adequate. Packed everything was in bags, expected to bend some conclusions, but not critical. Chips in the case of sop28 in the factory tape were not affected. Microcircuits of type 555 are mass and do not doubt their serviceability. I took for different projects as a setting generator and as a timer. As i apply, i will add a tip. All successful purchases!
