DDS IC Initiates Synchronized Signals
Direct-digital-synthesizer (DDS) technology allows a single source to precisely control signal frequency and phase with high-speed switching. But integrate multiple DDS devices on a single integrated circuit, and the capability expands to synchronized signal generation for a wide range of commercial and military applications. The new AD9958 dual-DDS and AD9959 quad-DDS devices offer such capability, with 32-b frequency tuning resolution, 10-b amplitude tuning resolution, and speeds to 500...

Integrated DDS Chip Takes Steps To 2.7 GHz
Direct-digital synthesis (DDS) has long promised precise, agile control of output waveforms, although limited in frequency and often in spurious performance. The AD9956 AgileRFTM DDS from Analog Devices, Inc. (Norwood, MA), however,...

400-MSamples/s DDSs Run On Only +1.8 VDC
Direct-digital synthesizers (DDSs) are flexible integrated circuits (ICs) capable of answering a host of design challenges. Programmable DDS ICs are agile frequency sources capable of low phase noise and good spurious performance. Until now, DDS...
