The AD9852 is a highly integrated digital synthesizer that uses advanced Direct Digital Synthesis (DDS) technology coupled with an internal high-speed, high-performance D/A converter. It generates a highly stable frequency-, phase-, and amplitude-programmable cosine output suitable for use as an agile local oscillator (LO) in communications, radar, and test and measurement equipment. The device features a 48-bit frequency resolution and can generate output signals at frequencies up to 150 MHz.
