W89C92 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.

W89C92 Maximum Ratings

SYMBOL	DESCRIPTION	MIN.	TYP	MAX.	UNIT
T_A	Ambient temperature	0	-	70	°C
T_S	Storage temperature	-65	-	150	°C
V_SS	Supply voltage	-	-	-12	V
V_IN	Input voltage	0	-	-12	V

Note: Exposure to conditions beyond those listed under Absolute Maximum Ratings may adversely affect the life and reliability of the device.

W89C92 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
