Analog Devices Unveils Industry's Fastest 12-bit, Direct Digital Synthesizers for Frequency-Agile Wireless Applications

Meeting the demand for direct digital synthesis (DDS) technology
that meets the needs of wireless applications requiring fast
hopping and/or sweeping, Analog Devices, Inc. (ADI), a global
leader in high-performance semiconductors for signal-processing
applications, today announced that it has more than tripled the
clock speed of previously available DDS integrated circuits (ICs).
Coupled with an on-chip, high-speed, 12-bit D/A converter, ADI's
AD9914 achieves a speed of 3.5 giga samples per second (GSPS),
while the AD9915 runs to 2.5 GSPS. Both device cores support
advanced digital programmable technology capable of synthesizing
frequency-agile, analog output sinusoidal waveforms at up to 1.4
GHz, such as those used in a wide range of communications
applications, such as wireless base stations, defense and
commercial radar, and secure communications systems.
Demonstrated in Analog Devices’ Booth #1725 at IMS2012 being
held this week, the new DDS devices feature a 32-bit parallel port
enabling extremely fast changes to frequency, phase, and the
amplitude of the output signal, and the programmable modulus
function which significantly extends the use of DDS ICs into
applications that require exact rational relationships such as
signal generators and other lab equipment..

“Increasing clock speeds to 3.5 GSPS on high-resolution DDS ICs
allows our customers to generate higher output frequencies with
improved dynamic performance,” said Peter Real, vice president,
linear and RF, Analog Devices. “ADI’s new DDS products represent a
significant step forward, providing better spurious free dynamic
range across a much broader frequency band when compared to
previous generations. By improving SFDR and enabling fast frequency
hopping and fine tuning resolution, AD9914 and AD9915 enable
designers to change frequencies in one clock period with
ultra-precise tuning of that frequency.”
The AD9914 and AD9915 settle in nanoseconds with granularity
well below 200 pHz. Other approaches, including FPGAs with embedded
DDS functions, have difficulty matching the SFDR (better than
-50dBc) of ADI’s DDS ICs on output signals over 1 GHz and require
higher operating power and the addition of a discrete D/A converter
to synthesize the sine wave.
AD9914 and AD9915 DDS IC Key Features:
- 12-bit D/A converter resolution and 3.5
GSPS (AD9914) and 2.5 GSPS (AD9915) clock rate
- Programmable modulus mode for precise
frequency generation and 64-bit resolution.
- Exceptional SFDR performance over a 1.5
GHz tuning range
- Dual accumulators for linear sweeping
of frequency, phase or amplitude
- 32-bit parallel port permits pin-access
to tuning words for fast and fine shift keying and hopping
- Consumes approximately 2.5 Watts at
full operating speed
