Description

The G261 LVD Regulator set is designed to provide

the correct reference voltages and bias currents for

LVD termination resistor networks (475Ω, 121Ω,and

475Ω) 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).

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 16pin SOP.
