Analog Devices AD9912 1 GSPS Direct Digital Synthesizer with 14-Bit DAC Datasheet
The AD9912 is a direct digital synthesizer (DDS) that features an integrated 14-bit digital-to-analog converter (DAC). It utilizes a 48-bit frequency tuning word to synthesize frequencies with step sizes as small as 4 µHz. The device includes an on-chip low noise PLL REFCLK multiplier and supports differential HSTL or single-ended CMOS comparators for feedback inputs.
The AD9912 operates over an industrial temperature range from −40°C to +85°C. It is available in two 64-lead LFCSP packages and offers software-controlled power-down modes. Key applications include agile LO frequency synthesis, low jitter clock generation, test equipment, wireless base stations, and secure communications.
