ORDERING INFORMATION

Le87270NQC

Le87270NQCT

16-pin QFN Green Package

Tray

Tape and Reel

The green package meets RoHS 2 Directive 2011/65/EU of the

European Council to minimize the environmental impact of electrical

equipment.

APPLICATIONS

•

VDSL2 Line Driver

ADSL2+ CPE Line Driver

The line driver gain is fixed internally. The amplifiers are

powered from a single supply.

Control pins can be used to adjust the supply current to

one-of-three or one-of-seven preset Bias level states and

a Standby state. The control pins respond to input levels

that can be generated with a standard tri-state GPIO.

The Le87270 is available in a 16-pin (4 mm x 4 mm) QFN

package with exposed pad for enhanced thermal

conductivity.

DESCRIPTION

The Le87270 is a single channel differential amplifier

designed to drive full rate VDSL2, as well as ADSL2+

signals with very low power dissipation. The Le87270

contains a pair of wideband amplifiers designed with

Microsemi’s HV15 Bipolar SOI process for low power

consumption.
