EVAL-CN0304-SDZ, Evaluation Board based on AD9834 75 MHz Low Power DDS Waveform Generator

Beschreibung

• EVAL-CN0304-SDZ, Evaluation Board for the AD9834, 75-MHz low power (25 mW total) direct digital synthesis (DDS) waveform generator. The output buffer and anti-imaging filter provide improved spectral performance, making it suitable for frequency generation or clocking applications requiring sine wave, triangular wave, and square outputs up to 18-MHz. Because they are sampled data devices, low power DDS devices must be followed by a suitable anti-imaging filter to remove spectral images. The combination of the DDS, output buffer and seventh-order elliptic low pass filter provides high quality spectral performance
