AD9915is a direct digital synthesizer (DDS) with a built-in 12-Bit
Digital-to-analog convertersTarget operating rates up to 2.5 GSPS. The device uses advanced DDS technology, along with a high-speed, high-performance DAC, to form a digitally programmable complete high-frequency synthesizer capable of generating frequency-agile analog output sine waves up to 1.4 GHz. The AD9915 is designed to provide fast frequency hopping and precision tuning resolution (32-bit in standard mode and 64-bit in programmable analog-to-digital mode). The device also implements fast phase and amplitude frequency hopping. Frequency tuning and control words are loaded into the AD9915 through serial or parallel I/O ports. It also supports operation in user-defined linear sweep mode to produce highly linear sweep waveforms of frequency, phase, or amplitude. A high-speed parallel data input port is also integrated to support high data rates for polar modulation schemes and fast programming of phase, frequency, and amplitude tuning words.
The AD9915 operates over the extended industrial temperature range (refer to the Absolute Maximum Ratings table in the data sheet).
