Intersil Introduces First-Ever VDSL2 Line Driver in Small 4mm x 5mm QFN Package

(PresseBox) (Milpitas, California, ) Intersil Introduces First-Ever VDSL2 Line Driver
in Small 4mm x 5mm QFN Package

MILPITAS, CA, June 19, 2007 – Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today announced the ISL1539, the latest addition to Intersil’s family of line drivers featuring low power, very small footprint and extremely good linearity. The ISL1539 is the first monolithic, dual port, DSL line driver for 100 Mbps VDSL2 Central Office (CO) applications.

The new ISL1539 uses proprietary circuitry to achieve low distortion, high capacitance drive and less than 910mW/port total power consumption while delivering 20.5dBm output power in 5-band VDSL2 applications. This driver uses Intersil’s own new high speed bipolar process technology to extend the performance of ADSL2, ADSL2+ and VDSL2 bandwidth high voltage line drivers.

The ISL1539 is a performance extension of Intersil’s ADSL2+ line drivers, thus this new driver supports full ADSL2+ fall back capability to drive long loop lengths at lower data rate as well as shorter loops at the full 100Mbps rates. Now DSL equipment designers can provide more flexible solutions, broader application range and higher value to telecom customers – all from one hardware design platform.

The design of the ISL1539, a current mode feedback DSL driver, has been optimized for high slew rate and low distortion in the 25kHz to 17MHz frequency bands. The ability of the driver to operate from power supplies up to 30V allows for use of transformer turns ratios that provide the highest receiver SNR for the central office VDSL2 chipsets. This eases the receiver specification requirements on the VDSL2 analog front ends and can also increase longer reach data rates.

The ISL1539’s extraordinary performance and small size enable designers to achieve very high port count VDSL2 line cards aimed at IP TV and video on-demand service applications. The dual port drivers are packaged in a tiny 4x5mm QFN package allowing the smallest footprint for VDSL2 applications. Low bias current, ease of use for high density PCB layout and a reduced number of external components provide unmatched performance and footprint features.

“Intersil is advancing our leadership in line drivers for the DSL industry,” said Kaveh Parsi, Director of Marketing for High Speed and Communications products at Intersil. “The ISL1539 provides our chipset partners and telecom customers the enabling performance to achieve the highest data rates in the industry.“

He added that Intersil is committed to developing new semiconductor processes in support of leading-edge products for low cost ADSL2+ and performance driven VDSL2 applications.

“We continue to integrate and simplify the line driver section of the xDSL systems and improve linearity vs. power to extend this technology towards higher and higher data rates,” Parsi concluded.

Pricing and Availability
The ISL1539 is available now in both 24-lead QFN and 24-lead HTSSOP packages and is priced from $3.73 to $3.83 each in 1,000-unit quantities. More information on the ISL1539 is available at http://www.intersil.com/cda/deviceinfo/0,1477,ISL1539,0.html
