"The Le87511 is a single channel line driver designed to work in home network G.hn power line communication systems. The Le87511 contains a pair of wideband amplifiers designed with Microsemi's HV30 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 four preset bias levels to optimize power and performance. A disable state forces the line driver into a low-power, high impedance mode for receive transmissions."
