W89C92
TRANSCEIVER FOR COAXIAL CABLE (TCC)
Publication Release Date: September 1994
- 1 -
Revision A3
GENERAL DESCRIPTION
The W89C92 Transceiver for Coaxial Cable (TCC) serves as an interface between the Attachment
Unit Interface and coaxial cable and implements the MAU functions required by a 10BASE2 or
10BASE5. The W89C92 provides transmit, receive, jabber lockup, SQE test, and collision presence
functions.
The W89C92 provides a functional solution for a 10BASE2 or 10BASE5 MAU. The power isolation
requirement of the MAU is met by using a DC-to-DC converter and a one-to-one ratio transformer.
FEATURES
Compatible with IEEE 802.3 10BASE2 and 10BASE5
CMOS process provides low power consumption
Mixed-mode circuit design integrates all transceiver electronics except signal and power isolation
and minimizes external component count
On-chip jabber timer and state machine meet the requirements for IEEE 802.3 MAU function
External selective SQE test function allows operation with IEEE 802.3 compatible repeater
Precision detection circuit design implements transmit mode collision detection
External selective jabber lockup function allows infinite data transmission
Standard 16-pin DIP and 28-pin PLCC package provide easy implementation of a MAU
