AD9952YSVZ-REEL7

Overview

The AD9952YSVZ-REEL7 is a direct digital synthesizer (DDS) featuring a 14-bit DAC and operating up to 400 MSPS. It generates frequency-agile analog output sinusoidal waveforms at up to 200 MHz using advanced DDS technology. The device provides fast frequency hopping and fine tuning resolution via a 32-bit frequency tuning word loaded through a serial I/O port. It operates over an extended industrial temperature range of −40°C to +105°C.

Feature Summary

• Integrated 14-bit DAC with high-speed performance
• 32-bit tuning word for precise frequency control
• PLL REFCLK multiplier supporting 4× to 20× multiplication
• Internal oscillator capable of driving from a single crystal

Applications

• Agile LO frequency synthesis
• Programmable clock generators
• Test and measurement equipment
• Acousto-optic device drivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type, temperature grade, and reel specifications. Ensure that the DVDD_I/O supply voltage matches the intended logic level requirements for the serial interface before finalizing procurement.

Selection Notes

Select this component when a single-channel DDS with a 14-bit DAC and 400 MSPS internal clock speed is required. Consider the 48-lead TQFP_EP package constraints and the need for external components such as the PLL loop filter and DAC reference resistor during the design phase.

Part Context

This part belongs to the Analog Devices AD9952 series of direct digital synthesizers. It is designed for applications requiring high-frequency signal generation with fast frequency agility. The device integrates a DDS core, a high-performance DAC, and a comparator within a single CMOS package.

Replacement Considerations

Consult official cross-reference lists or contact Analog Devices directly for verified substitute part numbers. Do not assume functional equivalence with other DDS models without verifying pin compatibility, electrical specifications, and register programming.
