Device Overview

Summary

The Le87281 is a single channel differential amplifier designed to drive G.Fast transmission signals as well as VDSL2 and ADSL2+ signals with very low power dissipation. The Le87281 contains a pair of wideband 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. The device can be programmed to one-of-three preset Bias levels or to impedance controlled Disable or Standby states. The control pins respond to input levels that can be generated with a standard tri-state GPIO.

Additional Features
  • Supports high frequency G.Fast transmission
  • Supports VDSL2 and ADSL2+ operation
  • Very low power dissipation
    • Class AB operation
  • 5 programmable states
  • No external gain resistors required
  • Small footprint package
    • 16-pin (4 mm x 4 mm) QFN
  • RoHS compliant
