The AD9852ASTZ is an integrated circuit (IC) component developed by Analog Devices. It is a highly integrated direct digital synthesizer (DDS) that offers excellent performance and flexibility for various applications. The IC operates in the frequency range of DC to 120 MHz and is commonly used in communication systems, test equipment, and instrumentation.
One of the key features of the AD9852ASTZ is its high-speed 14-bit digital-to-analog converter (DAC), which enables precise frequency control and generates highly accurate sinewave outputs. The DAC can provide output frequencies with a resolution as fine as 0.029 Hz. This allows for precise frequency tuning and modulation flexibility.
Another notable feature of the AD9852ASTZ is its 32-bit frequency tuning word (FTW), which allows for frequency agility and rapid frequency hopping. The FTW provides a high degree of control over the output frequency, enabling seamless frequency changes without any phase discontinuity. This feature is particularly useful in applications that require agile frequency synthesis.
The IC also includes a phase accumulator, up to a 48-bit wide, which allows for frequency control and phase modulation capabilities. It supports phase modulation schemes like phase shift keying (PSK) and quadrature amplitude modulation (QAM). Furthermore, the AD9852ASTZ supports multiplexed or independent 8-bit wide parallel or 3-wire serial programming interfaces, enabling easy control and data transfer with external devices
