KSZ8721BL - 3.3V Single Power Supply 10/100Base-TX/FX MII Physical Layer Transceiver

Download the KSZ8721BL datasheet PDF. This datasheet also covers the KSZ8721SL variant, as both devices belong to the same 3.3v single power supply 10/100base-tx/fx mii physical layer transceiver family and are provided as variant models within a single manufacturer datasheet.

Description

Operating with a 2.5V core to meet low-voltage and low-power requirements, the KS8721BL and KS8721SL are 10BASET/100BASE-TX/FX Physical Layer Transceivers that use MII and RMII interfaces to transmit and receive data.

Features

  • Single chip 100BASE-TX/100BASE-FX/10BASE-T physical layer solution.
  • 2.5V CMOS design; 2.5/3.3V tolerance on I/O.
  • 3.3V single power supply with built-in voltage regulator; Power consumption.

KS8721BL/SL Micrel KS8721BL/SL 3.3V Single Power Supply 10/100BASE-TX/FX MII Physical Layer Transceiver www.DataSheet4U.com Rev. 1.2 General Description Operating with a 2.5V core to meet low-voltage and low-power requirements, the KS8721BL and KS8721SL are 10BASET/100BASE-TX/FX Physical Layer Transceivers that use MII and RMII interfaces to transmit and receive data. They contain 10BASE-T Physical Medium Attachment (PMA), Physical Medium Dependent (PMD), and Physical Coding Sub-layer (PCS) functions. The KS8721BL/SL also have on-chip 10BASE-T output filtering. This eliminates the need for external filters and allows a single set of line magnetics to be used to meet requirements for both 100BASE-TX and 10BASE-T.
