Features & Applications
The KSZ9021RNI is a  3.465 V Gigabit Ethernet Transceiver with RGMII Support available in SMT QFN-48 Package. It is 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.

It 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.

Features:

  • Single-chip 10/100/1000Mbps IEEE 802.3 compliant Ethernet Transceiver
  • RGMII interface compliant to RGMII version 1.3
  • 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 1.2 V for the core
  • Jumbo frame support up to 16KB
  • 125MHz Reference Clock Output
  • Programmable LED outputs for link, activity and speed
  • Baseline Wander Correction

Applications:

  • Laser/Network Printer
  • Network Attached Storage (NAS)
  • Network Server
  • Gigabit LAN on Motherboard (GLOM)
  • Broadband Gateway
  • Gigabit SOHO/SMB Router
  • IPTV
  • IP Set-top Box
