AD9952YSVZ

Overview

The AD9952YSVZ is a direct digital synthesizer (DDS) featuring an integrated 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 the extended industrial temperature range of −40°C to +105°C.

Feature Summary

• Integrated 14-bit DAC with excellent dynamic performance
• PLL REFCLK multiplier supporting 4× to 20× multiplication
• Internal oscillator capable of being driven by a single crystal
• Multichip synchronization capability for system alignment

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type, temperature grade, and reel specifications. Confirm that the DVDD_I/O supply voltage matches the required logic level for your application before procurement.

Selection Notes

Select this component when high-speed frequency agility and precise phase control are required. Ensure the design accommodates the 1.8 V analog/digital core supplies and the 3.3 V or 1.8 V I/O supply. Verify that the external reference clock frequency falls within the supported input range for the desired PLL multiplication factor.

Part Context

The AD9952 belongs to the AD995x family of Direct Digital Synthesizers from Analog Devices. It shares functional similarities with other members like the AD9951 and AD9953 but is distinguished by its specific pinout, internal oscillator configuration, and performance characteristics tailored for high-frequency signal generation applications.
