Global Mixed-mode Technology Inc.

Low Voltage Differential (LVD) SCSI 27 Line Regu-

lator Set

Features

SCSI SPI-2 (Ultra 2), SPI-3 (Ultra 3/Ultra 160)

and SPI-4 (Ultra 320) LVD SCSI, 27 Line Low

Voltage Differential Regulator

4V to 5.25V Operation

Integrated Regulator Set for LVD SCSI

Differential Failsafe Bias

G261

Description

The G261 LVD Regulator set is designed to provide

the correct reference voltages and bias currents for

LVD termination resistor networks (475鈩? 121鈩? and

475鈩?. The device also provides a 1.3V output for

DIFFSENSE signaling. With the proper resistor net-

work, the G261 solution will meet the common mode

impedance, differential mode impedance, differential

bias voltage and common mode voltage requirements

of SPI-2 (Ultra2), SPI-3 (Ultra 3/Ultra 160) and SPI-4

(Ultra 320).

This device contains two sink / source reference volt-

age regulators, a 1.3V buffered output and protection

features. The protection features include thermal

shutdown and active current limiting circuitry. The

G261 is offered in 8 pin SOP and 16pin SOP.
