Direct digital synthesis (DDS) is a powerful technique for generating waveforms of arbitrary shape. It is used to synthesise an output signal of any defined frequency, phase and amplitude. One of the integrated circuits most extensively used to achieve these goals is the Analog Devices AD9837BCPZ-RL. This part is specifically designed for applications in which waveforms of fixed frequency need rapid, low phase noise production.The core device of the AD9837BCPZ-RL is the dual digital-to-analog converter (DAC). It operates at a 25 MHz clock rate and provides 8 bit resolution. An on-chip phase inverter provides for the simultaneous generation of complementary waveforms. The inverted waveform is delayed slightly to allow for the stable output of either a single waveform, or a pair of precisely synchronized complementary waveforms.The AD9837BCPZ-RL also offers several functions to improve the fidelity of the synthesized waveforms. These include an on-chip crystal oscillator which provides pin-selectable frequencies of 10, 25, 50 or 100 MHz, a phase-locked loop which locks the DAC output to a low-jitter clock source, and an adjustable output buffer amplifier which allows the output signal to be configured as either a single-ended signal or a differential signal.The AD9837BCPZ-RL is a highly specialized IC, and is primarily used in applications which require the rapid, low-noise synthesis of waveforms with fixed frequency. Some of these applications include frequency synthesis, signal generation, modulation, and test instrumentation.In frequency synthesis applications, the AD9837BCPZ-RL is used to generate signals of precise frequency and phase. These signals can be used to drive other components, such as mixers and oscillators. The ability to rapidly change frequency and output voltage allows the AD9837BCPZ-RL to be used in signal looking or automatic frequency tuning systems.The AD9837BCPZ-RL can also be used for signal generation and modulation purposes. It can be used to synthesize waveforms of various shapes and frequencies for signal processing applications. Furthermore, its adjustable output buffer amplifier allows the generated waveform to be configured for use in modulation or coding systems.Finally, the AD9837BCPZ-RL can be used for test and instrumentation purposes. Its high resolution and fast DACs allow for accurate measurement of signal parameters. In addition, the adjustable output buffer amplifier allows the output impedance to be adjusted to suit the impedance of the device under test.The AD9837BCPZ-RL is a highly versatile device which can be used in a variety of applications. Its powerful synthesis capabilities allow it to generate complex waveforms of precise frequency, amplitude and phase. Furthermore, its adjustable output buffer amplifier enables it to be configured for use in a variety of modulation and test systems.
