Product Overview


The KSZ8721BL is a single power supply 10/100BASE-TX/FX MII Physical-layer Transceiver, contains 10BASE-T Physical medium attachment (PMA), physical medium dependent (PMD) and physical coding sub-layer (PCS) functions. It also have on-chip 10BASE-T output filtering. This eliminates the need for external filters and allows a single set of line magnetic to be used to meet requirements for both 100BASE-TX and 10BASE-T. It is automatically configure themselves for 100 or 10Mbps and full- or half-duplex operation, using an on-chip auto-negotiation algorithm. The physical layer transceiver is ideal for 100BASE-TX/10BASE-T applications.
  • Single chip 100BASE-TX/100BASE-FX/10BASE-T physical layer solution
  • 2.5V CMOS design
  • <340mW Power consumption (including output driver current)
  • Fully compliant to IEEE 802.3u standard
  • Supports MII and reduced MII (RMII)
  • Supports 10BASE-T, 100BASE-TX and 100BASE-FX with Far_End_Fault detection
  • Supports power-down and power-saving modes
  • Configurable through MII serial management ports or via external control pins
  • On-chip, built-in, analogue front-end filtering for both 100BASE-TX and 10BASE-T
  • Supports MDI/MDI-X auto-crossover
