●The AD9958BCPZ is a 2-channel 500MSPS Direct Digital Synthesizer with 10-bit DACs that provide independent frequency, phase and amplitude control on each channel. This flexibility can be used to correct imbalances between signals due to analogue processing, such as filtering, amplification or PCB layout related mismatches. Because both channels share a common system clock, they are inherently synchronized. Synchronization of multiple devices is supported. It can perform up to a 16-level modulation of frequency, phase or amplitude (FSK, PSK, ASK). Modulation is performed by applying data to the profile pins. In addition, the AD9958 also supports linear sweep of frequency, phase or amplitude for applications such as radar and instrumentation. The serial I/O port offers multiple configurations to provide significant flexibility and SPI compatible mode of operation. The AD9958 uses advanced DDS technology that provides low power dissipation with high performance.
