AD9859YSVZ-REEL7

AD9859 is a direct digital synthesizer (DDS) featuring a 10bit DAC. The AD9859 uses advanced DDS technology, coupled with an internal high speed, high performance DAC to form a digitally programmable, complete high frequency synthesizer capable of generating a frequency-agile analogue output sinusoidal waveform at up to 200MHz. The AD9859 is designed to provide fast frequency hopping and fine tuning resolution(32-bit frequency tuning word). The frequency tuning and control words are loaded into the AD9859 via a serial I/O port. Typical application includes agile LO frequency synthesis, programmable clock generators test and measurement equipment commercial and amateur radio exciter.
