Description:
The Le87557 device is a single channel differential amplifier designed to drive full rate VDSL2, ADSL2+,\nand PLC high-power signals. The Le87557 device contains a pair of wide-band amplifiers designed with\nMicrochip’s HV15 bipolar SOI process for high-power output with low power consumption.\nLine driver gain is set externally to the device. The device can be powered from a single high-voltage\nsupply or from dual supplies.\nThe device can be programmed to one of three preset bias levels to optimize power and performance. In addition, the line driver features a power down state, which forces low-power and high-impedance mode for receive transmissions or for idle operations. The control pins respond to input levels that can be generated with a standard GPIO, but are tolerant of higher voltage logic levels. The Le87557device is available in a 16-pin (4 mm x 4 mm) QFN package with an exposed pad for enhanced thermal conductivity.
