Le87285
G.Fast Single Channel Line Driver
The Le87285 is a single channel line driver designed for home gateway applications. It supports
transmission xDSL and G.Fast signals with very low power dissipation. The Le87285 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.
