    產品詳情

    The AD9912 is a direct digital synthesizer (DDS) that features an integrated 14-bit digital-to-analog converter (DAC). The AD9912 features a 48-bit frequency tuning word (FTW) that can synthesize frequencies in step sizes no larger than 4 μHz. Absolute frequency accuracy can be achieved by adjusting the DAC system clock.

    The AD9912 also features an integrated system clock phase-locked loop (PLL) that allows for system clock inputs as low as 25 MHz.

    The AD9912 operates over an industrial temperature range, spanning ?40°C to +85°C.

    Applications

      Agile LO frequency synthesis

      Low jitter, fine tune clock generation

      Test and measurement equipment

      Wireless base stations and controllers

      Secure communications

      Fast frequency hopping
