AD9915BCPZ-REEL7

Overview

The AD9915BCPZ-REEL7 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 automatic linear and nonlinear frequency sweeping, a 32-bit parallel datapath interface, and eight frequency/phase offset profiles. Phase noise is specified at −128 dBc/Hz at a 1 kHz offset from 978 MHz, with wideband SFDR less than −57 dBc. Power supplies are 1.8 V and 3.3 V.

Feature Summary

• Advanced DDS technology coupled with a high-speed DAC for digitally programmable synthesis
• Programmable modulus mode enabling 64-bit fine tuning resolution
• Fast phase and amplitude hopping capability with user-defined linear sweep modes
• Multichip synchronization support for coordinated system operation

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 specific REEL7 suffix indicates tape-and-reel packaging when sourcing components. Confirm that the ordering information matches the required package type and quantity specifications provided by the manufacturer. Ensure compatibility with standard surface-mount assembly processes for the 88-lead LFCSP package.

Selection Notes

Select this component for applications requiring high-frequency agility and precise phase control. Evaluate the power supply requirements of 1.8 V and 3.3 V against system constraints. Consider the thermal performance characteristics and the need for external PLL loop filters if the internal multiplier is utilized for clock generation.

Part Context

This part belongs to the AD9915 family of direct digital synthesizers manufactured by Analog Devices Inc. It shares core functional specifications with other variants in the series but is distinguished by its specific packaging and reel configuration. The device integrates a complete high-frequency synthesizer solution within a single chip architecture.

Replacement Considerations

The AD9915BCPZ is a non-reel variant of the same component. Other members of the AD9915 family may offer similar functionality but require verification of pinout and electrical specifications before substitution.
