KS8721BL Datasheet 3.3v 10/100 Base-tx/fx Physical Layer Transceiver

Manufacturer: Micrel Semiconductor (now Microchip Technology)

Overview: .. .micrel. KS8721BL/SL Product Brief 3.3V 10/100BASE-TX/FX Physical Layer.

General Description

The KS8721BL/SL is a 10BASE-T, 100BASE-TX, and 100BASE-FX physical layer transceiver providing MII/ RMII interfaces to MACs and switches.

Using a unique mixed-signal design that extends signaling distance while reducing power consumption, the KS8721BL/SL represents Micrel’s fourth generation single-port Fast Ethernet PHY.

Micrel’s architecture dissipates an ultra-low 275mW in power, including transmit output drivers.

Key Features

  • Single chip 10BASE-T, 100BASE-TX, and 100BASE-FX physical layer solution.
  • Fully compliant to IEEE802.3u standards.
  • Low-power CMOS design, power consumption.
  • Supports media independent interface (MII) and reduced MII (RMII).
  • Delivers robust operation (130 meters+).
  • Furnishes Auto MDI/MDI-X.
  • Offers both power-down and power-saving modes.
  • Single 3.3V power supply.
  • Configurable through MII serial management ports or vi.
