AD9913:  Low Power 250 MSPS 10-Bit DAC 1.8 V CMOS Direct Digital Synthesizer

Product Description

The AD9913 is a complete direct digital synthesizer (DDS) designed to meet the stringent power consumption limits of portable, handheld, and battery-powered equipment. The AD9913 features a 10-bit digital-to-analog converter (DAC) operating up to 250 MSPS. The AD9913 uses advanced DDS technology, coupled with an internal high speed, high performance DAC to form a complete, digitally-programmable, high frequency synthesizer capable of generating a frequency agile analog output sinusoidal waveform at up to 100 MHz.

The AD9913 provides fast frequency hopping and fine tuning resolution. The AD9913 also offers fine resolution phase offset control. Control words are loaded into the AD9913 through the serial or parallel I/O port. The AD9913 also supports a user-defined linear sweep mode of operation for generating highly linearized swept waveforms of frequency. To support various methods of generating a system clock, the AD9913 includes an oscillator, allowing a simple crystal to be used as the frequency reference, as well as a high speed clock multiplier to convert the reference clock frequency up to the full system clock rate. For power saving considerations, many of the individual blocks of the AD9913 can be powered down when not in use.

The AD9913 operates over the extended industrial temperature range of −40°C to +85°C.
