Intersil Introduces Lowest Power, Dual Port, Class G Line

Intersil Introduces Lowest Power, Dual Port, Class G Line Driver 
ISL1561 Drops High Density DSLAM Port Power by > 30% 
MILPITAS, CA -- (Marketwire) -- 11/01/12 --  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:
