058 Hz or better frequency resolution 0.
022° phase tuning resolution Programmable modulus in frequency equation Phase noise ≤ –135 dBc per Hz @ 1 kHz offset (DAC output) (<115 dBc per Hz when using on-board PLL multiplier) Excellent dynamic performance >80 dB SFDR @ 100 MHz (±100 kHz offset) AOUT Automatic linear frequency sweeping capability 8 frequency or phase offset profiles 1.
8 V power supply Software and hardware controlled power-down Parallel and serial programming options 32-lead LFCSP package Optional PLL REF_CLK multiplier Internal oscillator (can be driven by a single crystal) Phase modulation capability APPLICATIONS Portable and handheld equipment Agile LO frequency synthesis Programmable clock generator FM chirp source for radar and scanning systems 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.
The AD9913 provides fast frequency hopping and fine tuning resolution.
The AD9913 also offers fine resolution phase offset control.
Control words are loaded into the AD9913 through the serial or parallel I/O port.
The AD9913 also supports a userdefined linear sweep mode of operation for generating highly linearized swept waveforms of frequency.
To support various methods of generating a system clock, the AD9913 includes an oscillator, allowing a simple crystal to be used as the frequency refere...
