  KSZ9021GN - Gigabit Ethernet Transceiver with GMII/MII Support
  Docket ↓
  KSZ9021GN
  Gigabit Ethernet Transceiver
  with GMII / MII Support General Description Features The KSZ9021GN is a completely integrated triple speed Single-chip 10/100/1000Mbps IEEE 802.3 compliant
  (10Base-T/100Base-TX/1000Base-T) Ethernet Physical
  Ethernet Transceiver
  Layer Transceiver for transmission and reception of data GMII/MII standard compliant interface
  on standard CAT-5 unshielded twisted pair (UTP) cable. Auto-negotiation to automatically select the highest link
  The KSZ9021GN provides the industry standard GMII/MII
  up speed (10/100/100Mbps) and duplex (half/full)
  (Gigabit Media Independent Interface / Media Independent On-chip termination resistors for the differential pairs
  Interface) for connection to GMII/MII MACs in Gigabit On-chip LDO controller to support single 3.3V supply
  Ethernet Processors and Switches for data transfer at
  operation – requires only external FET to generate 1.2V
  1000 Mbps or 10/100Mbps speed.
  for the core
  The KSZ9021GN reduces board cost and simplifies board Jumbo frame support up to 16KB
  layout by using on-chip termination resistors for the four 125MHz Reference Clock Output
  differential pairs and by integrating a LDO controller to
  drive a low cost MOSFET to supply the 1.2V core. Programmable LED outputs for link, activity and speed
  The KSZ9021GN provides diagnostic features to facilitate Baseline Wander Correction
  ®
  system bring-up and debugging in production testing and LinkMD TDR-based cable diagnostics for identification
  in product deployment. Parametric NAND tree support ...

  KSZ9021RL/RN - Gigabit Ethernet Transceiver with RGMII Support
  Docket ↓
  KSZ9021RL/RN
  Gigabit Ethernet Transceiver
  with RGMII Support
  Revision 1.2 General Description Features 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.
