Product Overview

The KSZ8721B is a 2.5V 10/100BaseTX/FX MII Physical Layer Transceiver operates at 2.5V to meet low voltage and low power requirements. The KS8721B/BT is a 10BaseT/100BaseTX/FX physical layer transceiver provides an MII to transmit and receive data. It contains the 10BaseT Physical Medium Attachment (PMA), Physical Medium Dependent (PMD) and Physical Coding Sub-layer (PCS) functions.
  • Single chip 100BaseTX/100BaseFX/10BaseT physical layer solution
  • 2.5V CMOS design, power consumption <200mW (excluding output driver current)
  • Fully compliant to IEEE 802.3u standard
  • Supports Media Independent Interface (MII) and Reduced MII (RMII)
  • Supports 10BaseT, 100BaseTX and 100BaseFX with Far_End_Fault detection
  • Supports power down mode and power saving mode
  • Configurable through MII serial management ports or via external control pins
  • Supports auto-negotiation and manual selection for 10/100Mbps speed and full/half-duplex mode
  • On-chip built-in analog front end filtering for both 100BaseTX and 10BaseT
  • LED outputs for link, activity, full/half duplex, collision and speed
  • Supports back to back, FX to TX for media converter applications
  • Supports MDI/MDI-X auto crossover
  • 2.5V/3.3V tolerance on I/O
