Analog Devices AD9854 Digital Synthesizer Data Sheet
The AD9854 is a highly integrated device that uses advanced Direct Digital Synthesis (DDS) technology coupled with two internal high-speed, high-performance quadrature DACs. It generates stable, frequency-phase, and amplitude-programmable sine and cosine outputs suitable for agile local oscillators in communications, radar, and test equipment applications.
The device provides 48-bit frequency resolution and supports simultaneous quadrature output signals up to 150 MHz. Key features include an internal programmable reference clock multiplier (4x to 20x), support for FSK, BPSK, PSK, and chirp operations, and a single-pin interface for conventional FSK and BPSK data.
