AD9914BCPZ Product details
GENERAL DESCRIPTION

The AD9914 is a direct digital synthesizer (DDS) featuring a 12-bit DAC. The AD9914 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 analog output sinusoidal waveform at up to 1.4 GHz. The AD9914 enables fast frequency hopping and fine tuning resolution (64-bit capable using programmable modulus mode). The AD9914 also offers fast phase and amplitude hopping capability.

The frequency tuning and control words are loaded into the AD9914 via a serial or parallel I/O port. The AD9914 also supports a user defined linear sweep mode of operation for generating linear swept waveforms of frequency, phase, or amplitude. A high speed, 32-bit parallel data input port is included, enabling high data rates for polar modulation schemes and fast reprogramming of the phase, frequency, and amplitude tuning words.

The AD9914 is specified to operate over the extended industrial temperature range (see the Absolute Maximum Ratings section).

AD9914BCPZ Frequently Asked Questions (FAQs)

What is the maximum clock frequency that can be used with the AD9914BCPZ?
The maximum clock frequency that can be used with the AD9914BCPZ is 1.4 GHz. However, the actual clock frequency used may be limited by the specific application and system requirements.

How do I optimize the spur performance of the AD9914BCPZ?
To optimize the spur performance of the AD9914BCPZ, it is recommended to use a high-quality clock source, minimize the noise on the clock input, and optimize the PLL loop filter components. Additionally, the use of a high-frequency clock and a high-OSR (oversampling ratio) can help to reduce spurs.

What is the maximum amplitude modulation frequency that can be achieved with the AD9914BCPZ?
The maximum amplitude modulation frequency that can be achieved with the AD9914BCPZ is approximately 100 MHz. However, the actual modulation frequency used may be limited by the specific application and system requirements.

How do I synchronize multiple AD9914BCPZ devices?
To synchronize multiple AD9914BCPZ devices, it is recommended to use a common clock source and to synchronize the devices using the SYNC_IN pin. Additionally, the use of a master-slave configuration can help to ensure that the devices are properly synchronized.

What is the typical power consumption of the AD9914BCPZ?
The typical power consumption of the AD9914BCPZ is approximately 1.6 W at a clock frequency of 1.4 GHz. However, the actual power consumption may vary depending on the specific application and system requirements.
