AD9954YSVZ

AD9954 is a direct digital synthesizer (DDS) that uses advanced technology, coupled with an internal high speed, high performance DAC to form a complete, digitally programmable, high frequency synthesizer capable of generating a frequency agile analogue output sinusoidal waveform at up to 160MHz. The AD9954 is programmed via a high speed serial I/O port. The device includes static RAM to support flexible frequency sweep capability in several modes, plus a user-defined linear sweep mode of operation. Typical applications include Agile LO frequency synthesis, programmable clock generators, FM chirp source for radar and scanning systems, automotive radars, test and measurement equipment and acousto-optic device drivers.
