Le87281
G.Fast Single Channel Line Driver
We are transitioning to Microchip; all product links will be directed to corresponding Le87281 product pages at www.microchip.com.
Overview
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 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.
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.
