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 Microchip'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.
Additional Features
Dual channel, VDSL2 35b profile, 20 dBm Line Driver
Very low power dissipation - Class H operation
Up to 16 programmable states
Small footprint package - 32-pin (5 mm x 5 mm) QFN
RoHS compliant
