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
