AD9952YSV

Overview

The AD9952YSV is a direct digital synthesizer (DDS) featuring an integrated 14-bit DAC operating up to 400 MSPS. It generates frequency-agile analog output sinusoidal waveforms at frequencies 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 on a 1.8 V power supply with support for 3.3 V input levels on most digital inputs, and is specified for the extended industrial temperature range of −40°C to +105°C.

Feature Summary

• Integrated 14-bit DAC with 400 MSPS internal clock speed
• 32-bit tuning word for precise frequency control
• PLL REFCLK multiplier supporting 4× to 20× multiplication
• On-chip comparator with 200 MHz toggle rate capability

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 and temperature grade. Confirm that the DVDD_I/O pin is powered correctly for the intended logic voltage level. Ensure proper board layout practices are followed for the exposed paddle ground connection to maintain signal integrity and thermal performance.

Selection Notes

Select this component when a high-speed, digitally programmable DDS is required with integrated DAC capabilities. Consider the 14-bit resolution and 400 MSPS clock speed for applications demanding wide bandwidth and low phase noise. Evaluate the need for the internal PLL multiplier and on-chip oscillator features versus external clocking solutions based on system complexity and jitter requirements.

Part Context

The AD9952 belongs to Analog Devices' family of Direct Digital Synthesizers designed for high-frequency signal generation. It combines a DDS core with a high-performance DAC in a single chip. The YSV suffix indicates a specific 48-lead TQFP_EP package variant suitable for surface mount applications within the extended industrial temperature range.
