FORT WORTH, Texas--(BUSINESS WIRE)--June 7, 2004

With new modeling data, Version 2.5 improves design accuracy,

accelerating time to market

Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, today announced the release of ADIsimPLL(TM) version 2.5, the most comprehensive design and evaluation tool available today for phase-locked loop (PLL) circuit design. Building on the popularity of over 10,000 downloads of previous versions that deliver excellent correlation between modeling predictions and bench measurements , the new ADIsimPLL software tool further removes time-consuming iterations from the design process, thereby speeding the design to market. This easy-to-use tool is offered as a free download from ADI's website. ADIsimPLL version 2.5 will be on display in Analog Devices' booth #847.

Version 2.5 provides new modeling data to support a broad range of recently announced ADI PLL products including:

-- the ADF4153 & ADF4154 fractional-N PLL synthesizers,

-- the ADF4360 integrated voltage-controlled oscillator PLL, and

-- the ADF702x family of UHF (ultrahigh frequency) transmitter

and transceiver ICs.

"With version 2.5 of ADIsimPLL, we are removing many traditional PLL design headaches," said Christian Kermarrec, vice president, RF and wireless systems, Analog Devices, Inc. "Using ADIsimPLL, engineers worldwide will find designing ADI PLLs into their products very practical and clear-cut."

Availability

ADIsimPLL Version 2.5 is available free of charge as a download, allowing designers to run simulations locally. ADIsimPLL may be downloaded from the Analog Devices' website at www.analog.com/pll.
