Analog Devices AD9850 Datasheet
The AD9850 is a highly integrated DDS synthesizer that combines a high‑speed 10‑bit DAC and a comparator to generate a spectrally pure sine‑wave output. It supports parallel‑byte or serial loading of a 32‑bit frequency tuning word and offers phase‑modulation capability with fine resolution.
The device is supplied in a 28‑lead SSOP package, operates from a single +3.3 V or +5 V supply, and is specified for an industrial temperature range of –40 °C to +85 °C. Detailed electrical characteristics, pin functions, and typical performance graphs are provided for clock‑generator and frequency‑agile applications.

Questions answered in these manuals
What is the maximum clock input frequency for the AD9850?
With a +5 V supply the AD9850 accepts up to 125 MHz, and with a +3.3 V supply up to 110 MHz.
How much power does the AD9850 consume in power‑down mode?
In power‑down the device draws about 30 mW on a +5 V supply and about 10 mW on a +3.3 V supply.
What is the maximum output frequency of the AD9850?
The device can generate output frequencies up to one‑half the reference clock frequency, e.g., 62.5 MHz when using a 125 MHz reference.
What is the frequency tuning resolution of the AD9850?
With a 125 MHz reference clock the tuning resolution is 0.0291 Hz.
How much power does the AD9850 consume at 125 MHz with a +5 V supply?
It consumes 380 mW at 125 MHz with a +5 V supply.
