AD9910BSVZ, Цифровой синтезатор, 14-бит, 1 GSPS, 3.3В CMOS [TQFP-100]

The AD9910 series CMOS Direct Digital Synthesizer featuring an integrated 14-bit DAC and supporting sample rates up to 1 GSPS. The AD9910 employs an advanced, proprietary DDS technology that provides a significant reduction in power consumption without sacrificing performance. The DDS/DAC combination forms a digitally programmable, high frequency, analog output synthesizer capable of generating a frequency agile sinusoidal waveform at frequencies up to 400MHz. The user has access to the three signal control parameters that control the DDS, frequency, phase and amplitude. The DDS provides fast frequency hopping and frequency tuning resolution with its 32-bit accumulator. With a 1 GSPS sample rate, the tuning resolution is ~0.23Hz. The DDS also enables fast phase and amplitude switching capability. The AD9910 is controlled by programming its internal control registers via a serial I/O port.
