  MILPITAS, CA, Nov 01 (Marketwire) -- 
Intersil Corporation (NASDAQ: ISIL), a world leader in the design and
manufacture of high-performance analog and mixed signal semiconductors,
today extends its 20-year history of providing leading-edge products to
the central office DSLAM market with the introduction of the ISL1561, the
most power-efficient Class G line driver. 

    Designed for existing and emerging xDSL central office reference designs
with significant improvements over Class H solutions, the ISL1561
provides backward compatibility to existing +14V systems. Its industry
leading design supports another 10% power savings in emerging +12V single
supply systems.

    Each of the two ports is internally configured for a fixed 11.6V/V gain
using a specific external build out resistor and a cross-coupled
feedback, providing active output impedance with reduced losses. A
three-pin serial interface allows each port to be separately tuned to the
minimum required quiescent current for the intended signal standard. Two
external supply voltage boost caps provide a brief peak in the total
output stage voltage to supply the peak line voltages using a control
signal from the AFE.

    Features and Benefits


--  Nominal quiescent current to support full line power for ADSL2+ is
    only 8mA/port; VDSL2+ 8b is 10mA/port; and VDSL2+ 17a is only
    12mA/port
--  For the most demanding 8b profile, total quiescent power to deliver
    19.5dBm to the line is reduced from > 900mW/port to Signal peaks
    maintains a signal linearity comparable to much higher power +24V
    class AB solutions

    

Pricing and Availability
 The ISL1561 is available now in compact
24-lead QFN packages, with prices starting at $2.57 each in 1,000-unit
quantities. For more information please visit:
