AD9852ASVZ

Overview

The AD9852ASVZ is a CMOS 300 MSPS complete Direct Digital Synthesis (DDS) digital synthesizer manufactured by Analog Devices Inc. It features dual integrated 12-bit D/A converters and an ultrahigh-speed comparator with 3 ps rms jitter. The device supports FSK, BPSK, PSK, chirp, and AM operation, offering excellent dynamic performance with 80 dB SFDR at 100 MHz on the AOUT pin. It includes a programmable reference clock multiplier ranging from 4× to 20×, dual 48-bit frequency registers, and dual 14-bit phase offset registers. Operating on a single 3.3 V supply, it provides serial or parallel control interfaces and functions as an agile LO, programmable clock generator, or RF exciter.

Feature Summary

• Dual integrated 12-bit DACs for high-performance signal synthesis
• Programmable reference clock multiplier supporting 4× to 20× multiplication
• Ultrahigh-speed comparator with minimal jitter for clock generation
• Support for multiple modulation modes including FSK, BPSK, and chirp

Applications

• Agile local oscillator frequency synthesis
• Programmable clock generator applications
• FM chirp source for radar and scanning systems
• Test and measurement equipment
• Commercial and amateur RF exciter

Procurement Notes

Verify the specific suffix ASVZ against the official datasheet ordering guide to confirm the maximum clock frequency rating of 300 MHz and the industrial temperature range specifications. Ensure that the package type matches the required thermal management guidelines, particularly regarding the exposed pad soldering requirements for the TQFP variant.

Selection Notes

Select the AD9852ASVZ when a system requires a 300 MHz internal clock rate compared to the lower-rated variants. Confirm that the application utilizes the dual 12-bit DAC architecture and requires the extended industrial operating temperature range. Verify interface compatibility with either the 10 MHz serial SPI or 100 MHz parallel programming modes.

Part Context

The AD9852ASVZ belongs to the AD9852 family of direct digital synthesizers. It is pin-for-pin compatible with the AD9854 single-tone synthesizer but offers distinct DDS core capabilities. The ASVZ suffix specifically denotes the version rated for higher internal clock frequencies up to 300 MHz, distinguishing it from other regional or speed-graded variants within the same product line.

Replacement Considerations

The AD9852ASTZ is a confirmed substitute part number within the same family. Note that the ASTZ variant has a maximum internal clock frequency limit of 200 MHz, which differs from the 300 MHz capability of the ASVZ.
