Overview

Order this document by MC34055/D IEEE 802.3 10BASE-T Transceiver The Motorola 10BASE–T transceiver, designed to comply with the ISO 8802–3 [IEEE 802.3] 10BASE–T specification, will support a Medium Dependent Interface (MDI) in an embedded Media Attachment Unit (MAU)*.

The interface supporting the Data Terminal Equipment (DTE) is TTL, CMOS, and raised ECL compatible, and the interface to the Twisted Pair (TP) media is supported through standard 10BASE–T filters and transformers.

Differential data intended for the TP media is provided a 50 ns pre–emphasis and data at the TP receiver is screened by Smart Squelch circuitry for specific threshold, pulse width, and sequence requirements.

Key Features

  • of the MC34055 include: Collision and Jabber detection status outputs, select mode pins for forcing Loop Back and Full.
  • Duplex operation, a Signal Quality Error pin for testing the collision detect circuitry without affecting the TP output, and a LED driver for Link Integrity status. An on.
  • chip oscillator, capable of receiving a clock input or operating under crystal control, is also provided for internal timing and driving a buffered clock output. The MC34055 is manufactured on a.
