Analog Devices - Press Release 12-10-2007
Analog Devices' Innovative Direct Digital Synthesis Technology Now Available
for Low-Power, Portable Electronics
Consuming just 50 mW of power at a 250-MHz clock rate, ADI's
direct digital synthesis IC delivers price and performance to mobile
industrial and communications devices.
-- Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance
semiconductors for signal processing applications, is expanding the
applicability of its industry leading direct digital synthesis technology
into battery-powered industrial, communications and defense electronics
applications with the introduction of a complete low-power, low-cost
Direct Digital Synthesizer (DDS) specifically designed for wireless,
handheld equipment. Unlike competing approaches used to synthesize a
digitally controlled frequency, the AD9913 is the first DDS device to
deliver a 250-MHz clock rate while consuming as little as 50 mW of power.
At less than $5 in volume quantities and available in a compact chip-scale
package, the new IC is ideally suited for portable barcode scanners,
radar detectors, remote radio controls and other products that require
a cost-effective combination of performance and low-power operation.
Unlike phase-locked loop (PLL) devices, which suffer from settling
times measured in microseconds and fine-tuning limitations, the AD9913
settles in nanoseconds with granularity well below 10 mHz. Other approaches,
including field-programmable gate arrays (FPGAs) with embedded DDS functions,
have difficulty matching the AD9913's greater than 80-dB spurious-free
dynamic range (SFDR) performance on a 100-MHz output signal while requiring
higher operating power and the addition of a discrete digital-to-analog
converter (DAC) to synthesize the sine wave. The AD9913 includes an
on-chip 10-bit high-speed DAC with no price premium compared to a stand-alone
DAC. The fine-tuning granularity and higher SFDR of the AD9913 allow
it to more quickly and accurately generate a stable signal in the band
of interest. In a remote radio-controlled application, for example,
such as an unmanned aircraft, this means the operator is less likely
to lose contact with the airplane due to frequency interference that
can result in a dropped signal.
"Larger systems like wireless
base stations and test and measurement equipment have been taking advantage
of the higher operating-frequency ranges, faster linear frequency hopping
and other performance benefits of DDS technology for the better part
of a decade," said Kevin Kattmann, product line director of High-Speed
Signal Processing, Analog Devices. "With the launch of the AD9913, designers
of battery-powered devices can now incorporate the same faster switching
speeds, fine frequency resolutions and broader frequency spectrum into
their products with no price or power penalty."
The AD9913 is available in full production quantities.
The AD9913 costs $4.65 per unit in 100,000-unit quantities and is available
in a 32-lead LFCSP (lead-frame chip-scale package). For more information,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
