1 GSPS, 14-Bit, 3.3 V CMOS Direct Digital Synthesizer Data Sheet AD9910 Rev. D is a frequency synthesizer produced by American Analog Devices company. Its main features are the internal clock speed up to 1 GSPS, support for 14-bit DAC, frequency resolution up to 0.23 Hz, phase noise as low as -125 dBc/Hz @ 1 kHz offset (400 MHz carrier), and excellent dynamic performance with bandwidth SFDR up to >80 dB.
The AD9910 Direct Digital Synthesizer (DDS) integrates a 14‑bit DAC and supports sample rates up to 1 GSPS. It provides a frequency resolution of about 0.23 Hz, phase‑noise performance of ≤ −125 dBc/Hz at 1 kHz offset, and an analog output bandwidth up to 400 MHz.
The device includes serial and parallel I/O, programmable RAM for waveform storage, and multichip synchronization. It is supplied in a 100‑lead thin‑quad flat package and is targeted at radar, test‑and‑measurement, acousto‑optic drivers, and fast frequency‑hopping applications.
