The Le87270 is a single channel differential amplifier designed to drive full rate of VDSL2, as well as ADSL2 and ADSL2+ signals with very low power dissipation. The Le87270 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-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.
Additional Features
VDSL2 30a profile, 14.5 dBm Line Driver
Very low power dissipation - Class AB operation
Up to 8 programmable states
No external gain resistors required
Small footprint package - 16-pin (4 mm x 4 mm) QFN
RoHS compliant
