W89C92

TRANSCEIVER FOR COAXIAL CABLE (TCC)

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
