Richardson RFPD Introduces New 3.5 GSPS Direct Digital Synthesizer With 12-Bit DAC From ADI

Digitally programmable, complete high frequency DDS capable of generating frequency-agile analog output sine wave at up to 1.4 GHz

LaFox, Illinois: Richardson RFPD, Inc. recently announces immediate availability and full design support capabilities for a new direct digital synthesizer (DDS) featuring an internal, high speed, high performance, 12-bit digital-to-analog converter (DAC) from Analog Devices, Inc. (ADI).

The AD9914 is a complete high frequency synthesizer capable of generating a frequency-agile analog sinusoidal waveform (sine wave) at up to 1.4 GHz. The device enables fast frequency hopping and fine tuning resolution — 64-bit capable using the programmable modulus mode. It also offers fast phase and amplitude hopping. The frequency tuning and control words are loaded into the DDS via a serial or parallel I/O port. The new device supports a user-defined linear sweep mode of operation for generating linear swept waveforms of frequency, phase, or amplitude. A high speed, 32-bit parallel data input port is included, enabling high data rates for polar modulation schemes and fast reprogramming of the phase, frequency and amplitude tuning words.

Additional key features of the AD9914 include:

• 3.5 GSPS internal clock speed
• Frequency tuning resolution to 190 pHz
• 16-bit phase tuning resolution
• 12-bit amplitude scaling
• 8 frequency/phase offset profiles
• Phase noise: −128 dBc/Hz (1 kHz offset at 1396 MHz)
• Wideband SFDR < −50 dBc
• 1.8 V/3.3 V power supplies
• 88-lead LFCSP package

The AD9914 is ideally-suited for radar and scanning systems, test and measurement equipment, and agile LO frequency synthesis applications. It is part of ADI's Select Products for Q4, 2012.

Common configurations are in stock and available for immediate delivery. To find more information, or to purchase the device today on the Richardson RFPD website, please visit the AD9914 webpage. The device is also available by calling 1-800-737-6937 (within North America); or please find your local sales engineer (worldwide) at Local Sales Support.
