AD9951YSVZ, Цифровой синтезатор, 14-бит, 400 MSPS, 1.8В CMOS [TQFP_EP-48]

The AD9951YSVZ is a Direct Digital Synthesizer (DDS) featuring a 14-bit DAC operating up to 400MSPS. This uses advanced DDS technology, coupled with an internal high speed, high performance DAC to form a digitally programmable, complete high frequency synthesizer capable of generating a frequency-agile analogue output sinusoidal waveform at up to 200MHz. This is designed to provide fast frequency hopping and fine tuning resolution (32-bit frequency tuning word). The frequency tuning and control words are loaded into this via a serial I/O port.

• 32-bit Tuning word
• Phase noise <=-120dBc/Hz at 1kHz offset (DAC output)
• Excellent dynamic performance
• Serial I/O control
• 1.8V Power supply
• Software and hardware controlled power-down
• Support for 5V input levels on most digital inputs
