AD9959 Double wayDDSModularV4.0

1 Module introduction

AD9959Consists of four direct digital synthesizersDDSThe kernel consists of each channel providing independent frequency, phase and amplitude control, each with independent high-speed10BitDACEach channel is dedicated32Bit frequency control word,14Bit phase offset and10Bit output proportional multiplier. The utility model can be used for correcting signals, such as filtering, amplifying, etc.PCBThe imbalance caused by layout mismatches. Since all channels share a common system clock, they have inherent synchronization and support synchronization of multiple devices.

AD9959You can execute as many as16A frequency, phase, or amplitude modulationFSK,PSK,ASK). You can perform modulation by applying data to the mode pin. Besides,AD9959It also supports linear frequency, amplitude or phase scanning, and is suitable for radar, instrumentation and other applications.
