Key benefits - Improved waveform quality with a 70 MHz low-pass filter, delivering a better signal-to-noise ratio. - Pin-accessible amplitude control: a PIN provides access to the DA reference for convenient output amplitude adjustment to your application. - Flexible rectangular-wave duty cycle: adjusting the variable resistor changes the reference input voltage of the comparator to yield different duty cycles. - Stable and precise oscillators: AD9850 module uses a 125 MHz active oscillator; AD9851 module uses a 30 MHz active oscillator for reliable frequency generation. Specifications - 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 - Data input: supports parallel or serial data input - Amplitude adjustment: pin-accessable DA reference for easy amplitude tuning - Duty cycle: adjustable via the variable resistor - Oscillators: stable 125 MHz (AD9850) and 30 MHz (AD9851) - Size: 4.5 x 2.6 cm Use scenarios - Lab signal generator for RF front-end testing and calibration of DAC/ADC systems - Microcontroller timing reference and waveform generation for digital projects - Bench-top experiments requiring precise, repeatable sine and square waves across a range up to 40 MHz
