AD9914BCPZ

AD9914 is a direct digital synthesizer (DDS) featuring a 12bit DAC. It 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 1.4GHz. It enables fast frequency hopping and fine tuning resolution (64bit capable using programmable modulus mode). It also offers fast phase and amplitude hopping capability. Application includes agile LO frequency synthesis, programmable clock generator, FM chirp source for radar and scanning systems, test and measurement equipment, acousto-optic device drivers, polar modulator, fast frequency hopping.

• 3.5GSPS internal clock speed, integrated 12bit DAC
• 16bit phase tuning resolution, 12bit amplitude scaling
• Programmable modulus, automatic linear and nonlinear frequency sweeping capability
• 32-bit parallel data path interface, 8 frequency/phase offset profiles
• Serial or parallel input/output control, software and hardware controlled power-down
• PLL REF CLK multiplier, phase modulation capability, amplitude modulation capability
• DVDD-I/O range from 3.135 to 3.465V (pin 16, pin 83, AVDD (1.8V) and DVDD (1.8V)=1.8V ± 5%)
• Typical base DDS power, PLL disabled is 2392mW (AVDD (1.8V) and DVDD (1.8V)=1.8V ± 5%, TA=25°C)
• Typical modulus additional power is 20mW (AVDD (1.8V) and DVDD (1.8V)=1.8V ± 5%, TA=25°C)
• 88-lead LFCSP package, temperature range from -40°C to +85°C
