Le87290
VDSL2 Dual Channel Line Driver
We are transitioning to Microchip; this page will be directed to Le87290 product page at www.microchip.com.
Overview
The Le87290 is a dual channel differential amplifier designed to drive full rate of VDSL2, as well as ADSL2 and ADSL2+ signals with very low power dissipation. The Le87290 contains a pair of wide band amplifiers designed with Microsemi's HV15 Bipolar SOI process for low power consumption. 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-sixteen 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.
