AD9913BCPZ-REEL71中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The AD9913 is a complete direct digital synthesizer (DDS) designed to meet the stringent power consumption limits of portable, handheld, and battery-powered equipment. The AD9913 features a 10-bit digital-to-analog converter (DAC) operating up to 250 MSPS. The AD9913 uses advanced DDS 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 analog output sinusoidal waveform at up to 100 MHz.
