KS8721BT Datasheet 2.5v 10/100bastx/fx Mii Physical Layer Transceiver

Manufacturer: Micrel Semiconductor (now Microchip Technology)

Overview: KS8721B/BT 2.5V 10/100BasTX/FX MII Physical Layer Transceiver Rev. 2.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

Operating at 2.5 volts to meet low voltage and low power requirements, the KS8721B/BT is a 10BaseT/100BaseTX/FX Physical Layer Transceiver, which 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.

Moreover, the KS8721B/BT has on-chip 10BaseT output filtering, which eliminates the need for external filters and allows a single set of line magnetics to be used to meet requirements for both 100BaseTX and 10BaseT.

Key Features

  • Single chip 100BaseTX/100BaseFX/10BaseT physical layer solution.
  • 2.5V CMOS design, power consumption.
