AD9954YSVZ Datasheet PDF - ADI

●The AD9954YSVZ is a 400MSPS 1.8V CMOS Direct Digital Synthesizer that uses advanced technology coupled with an internal high speed, high performance DAC to form a complete, digitally programmable and high frequency synthesizer capable of generating a frequency-agile analogue output sinusoidal waveform at up to 160MHz. The AD9954 enables fast frequency hopping coupled with fine tuning of both frequency (0.01Hz or better) and phase (0.022° granularity). It 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. An on-chip high speed comparator is also included for applications requiring a square wave output. An on-chip oscillator and PLL circuitry provide users with multiple approaches to generate the device"s system clock.
