AD9854AST
CMOS 300 MSPS Quadrature Complete DDS, Analog Devices, RoHS, LQFP80

The AD9854 digital synthesizer is a highly integrated device that uses advanced DDS technology, coupled with two internal high speed, high performance quadrature DACs to form a digitally programmable I and Q synthesizer function. When referenced to an accurate clock source, the AD9854 generates highly stable, frequency-phase, amplitude-programmable sine and cosine outputs that can be used as an agile LO in communications, radar, and many other applications. The innovative high speed DDS core of the AD9854 provides 48-bit frequency resolution (1 µHz tuning resolution with 300 MHz SYSCLK). Maintaining 17 bits ensures excellent SFDR.
