Product Description

GENERAL DESCRIPTION
The AD9852 digital synthesizer is a highly integrated device that uses advanced DDS technology, coupled with an internal high speed, high performance D/A converter to form a digitally programmable, agile synthesizer function. When referenced to an accurate clock source, the AD9852 generates a highly stable frequency-, phase-, and amplitude-programmable cosine output that can be used as an agile LO in communications, radar, and many other applications. The innovative high speed DDS core of the AD9852 provides 48-bit frequency resolution (1 μHz tuning resolution with 300 MHz SYSCLK). Maintaining 17 bits ensures excellent SFDR.
