Key benefits - Improved waveform quality with a 70 MHz low-pass filter, delivering better signal-to-noise ratio for your tests and measurements. - Pin-accessible amplitude control: a dedicated pin provides easy access to the DAC reference for convenient output amplitude adjustment to suit specific applications. - Flexible rectangular wave initiation and duty cycle: adjustable via a variable resistance that changes the reference input voltage of the comparator, allowing different duty cycles of the rectangular output. - Stable and precise oscillators: AD9850 module uses a 125 MHz active oscillator, while AD9851 uses a 30 MHz active oscillator, ensuring reliable frequency generation. - Flexible data input: supports both parallel and serial data input options for integration with different controller interfaces. What it includes and how it works - Frequency range (AD9850): 0-40 MHz - Outputs: two sine waves and two square waves - Harmonic distortion: may increase above 20-30 MHz - Square wave frequency: 0-1 MHz - Waveform quality: enhanced by the 70 MHz low-pass filter - Data input: selectable between parallel and serial - Amplitude adjustment: accessible pin for easy amplitude control - Duty cycle adjustment: via variable resistance on the reference input - Oscillators: stable 125 MHz (AD9850) and 30 MHz (AD9851) physical size - Size: 4.5 x 2.6 cm 2-3 use scenarios - Laboratory signal generator: produce clean sine and square waves with adjustable amplitude to test ADCs, DACs, and other front-end circuits across 0-40 MHz. Use the accessible amplitude pin and the 70 MHz LPF for optimal SNR. - RF and communications prototyping: generate DDS-based waveforms for RF circuit testing, with parallel or serial data input for flexible controller compatibility; adjust duty cycle to match timing requirements of square-wave signaling. - Electronics bench testing and integration: implement compact test signals in prototyping boards, leveraging the stable AD9850/AD9851 oscillators and configurable waveform outputs to validate performance under real-world conditions.
