AD9914BCPZ-REEL7

Overview

The AD9914BCPZ-REEL7 is a direct digital synthesizer (DDS) featuring an integrated 12-bit DAC. It operates with a maximum internal clock speed of 3.5 GSPS and generates frequency-agile analog output sinusoidal waveforms up to 1.4 GHz. The device provides a frequency tuning resolution down to 190 pHz, a 16-bit phase tuning resolution, and 12-bit amplitude scaling. It supports serial or parallel input/output control interfaces and utilizes 1.8 V/3.3 V power supplies. The component is housed in an 88-lead LFCSP package.

Feature Summary

• Integrated high-speed 12-bit DAC for complete high-frequency synthesis
• Supports fast frequency hopping and fine-tuning resolution via programmable modulus mode
• Includes automatic linear and nonlinear frequency sweeping capability
• Features a 32-bit parallel datapath interface for polar modulation schemes

Applications

• Agile LO frequency synthesis
• Programmable clock generator
• FM chirp source for radar and scanning systems
• Test and measurement equipment
• Acousto-optic device drivers

Procurement Notes

Verify the REEL7 suffix indicates reel packaging when sourcing. Confirm the specific B-grade temperature range against project requirements. Ensure ESD precautions are implemented during handling due to sensitivity. Validate pin compatibility with the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high-speed direct digital synthesis with integrated conversion capabilities. Consider the 88-lead LFCSP package size for board space constraints. Evaluate the 1.8 V and 3.3 V supply requirements against available system power rails. Assess thermal dissipation needs given the specified power consumption levels at maximum clock speeds.

Part Context
