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: www.intersil.com/products/ISL1561
