LE87281NQCT

Le87281 G.Fast Single Channel Line Driver 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.
