AD9954YSV-REEL7

Overview

The AD9954YSV-REEL7 is a direct digital synthesizer (DDS) manufactured by Analog Devices Inc. It integrates a high-speed, high-performance 14-bit DAC to form a complete, digitally programmable frequency synthesizer. The device generates frequency-agile analog output sinusoidal waveforms at up to 160 MHz with an internal clock speed of 400 MSPS. Key specifications include 32-bit frequency tuning accuracy and 14-bit phase tuning accuracy. It features automatic linear and nonlinear frequency sweeping, serial I/O control, and supports 5 V input levels on most digital inputs.

Feature Summary

• Integrates a 14-bit DAC for high-frequency synthesis
• Supports automatic linear and nonlinear frequency sweeping
• Provides software and hardware controlled power-down modes

Applications

• Agile LO frequency synthesis
• Programmable clock generators
• FM chirp source for radar and scanning systems
• Automotive radars
• Test and measurement equipment

Procurement Notes

Verify the specific suffix REEL7 indicates reel packaging when sourcing. Confirm the component matches the AD9954 family specifications. Ensure compatibility with 1.8 V power supply requirements. Check for RoHS compliance status in official documentation. Validate pinout alignment for 48-lead TQFP integration.

Selection Notes

Select this component for applications requiring precise frequency agility and fast switching speeds. Consider the 400 MSPS internal clock speed for signal generation needs. Evaluate the 14-bit DAC resolution against system dynamic range requirements. Assess the need for integrated RAM for sweep patterns. Verify interface compatibility with existing control logic.

Part Context
