Product Summary

The AD9850BRS is a highly integrated device that uses advanced DDS technology coupled with an internal high speed, high performance, D/A converter and comparator, to form a complete digitally programmable frequency synthesizer and clock generator function. When referenced to an accurate clock source, the AD9850BRS generates a spectrally pure, frequency/phase-programmable, analog output sine wave. The applications of the AD9850BRS include Frequency/Phase–Agile Sine-Wave Synthesis, Clock Recovery and Locking Circuitry for Digital Communications, Digitally Controlled ADC Encode Generator and Agile Local Oscillator Applications.
