AD9915BCPZ

Overview

The AD9915BCPZ is a direct digital synthesizer (DDS) featuring an integrated 12-bit DAC. It operates with a 2.5 GSPS internal clock speed and generates frequency-agile analog output sinusoidal waveforms up to 1.0 GHz. The device supports fast frequency hopping, fine tuning resolution to 135 pHz, and 16-bit phase tuning resolution. It includes a 32-bit parallel datapath interface, eight frequency/phase offset profiles, and automatic linear/nonlinear frequency sweeping. Power supplies are 1.8 V for the core and 3.3 V for I/O. The component is housed in an 88-lead LFCSP package.

Feature Summary

• Integrated 12-bit DAC with high-speed performance
• Programmable modulus mode for fine tuning resolution
• Automatic linear and nonlinear frequency sweeping capability
• Supports serial or parallel input/output control interfaces

Applications

• Agile LO frequency synthesis
• Programmable clock generator
• FM chirp source for radar and scanning systems
• Test and measurement equipment
• Fast frequency hopping

Procurement Notes

Verify the specific suffix BCPZ against the manufacturer's current ordering guide to confirm package type and temperature range specifications. Ensure compatibility with required voltage levels and interface protocols before procurement. Cross-reference the revision history for any updates to electrical characteristics that may impact system design.

Selection Notes

Select this component when a high-speed DDS with integrated DAC is required for applications demanding precise frequency agility and low phase noise. Consider the 88-lead LFCSP package constraints and thermal management requirements. Evaluate the need for parallel versus serial programming interfaces based on system complexity and data throughput requirements.

Part Context

The AD9915BCPZ belongs to the Analog Devices AD9915 family of direct digital synthesizers. It shares functional similarities with other members like the AD9914 but offers distinct clock speeds and performance metrics. This part number specifically denotes the commercial grade version in the LFCSP package, designed for industrial temperature ranges.

Replacement Considerations

The AD9915BCPZ-REEL7 is a reel-packaged alternative from the same manufacturer. Verify pinout compatibility and electrical specifications before substitution. Other family members may require significant circuit redesign due to differing interface or power requirements.
