DDS39RF10ACK

Overview

The DDS39RF10ACK is a specialized multi-Nyquist direct digital synthesizer manufactured by Texas Instruments. It features a 16-bit resolution with two independent DAC channels, operating at a maximum sampling rate of 20.48 GSPS and supporting output frequencies up to 12 GHz. The device utilizes an FCBGA-256 package and operates within a supply voltage range of 1.71 V to 1.89 V. It includes four integrated digital upconverters (DUCs) with interpolation factors of 4x, 6x, 8x, and 12x, alongside a 64-bit NCO for phase-coherent frequency hopping. The component supports JESD204B/C interfaces with data rates up to 12.8 Gbps per lane.

Feature Summary

• High-speed 16-bit dual-channel DAC architecture enabling direct RF signal generation in C and X bands
• Integrated digital upconversion with flexible interpolation ratios and complex baseband processing capabilities
• JESD204C compliant serial interface ensuring deterministic latency and multi-device synchronization via SYSREF

Applications

• Satellite communication (SATCOM) systems requiring high-frequency agility
• Phased array antenna beamforming networks
• Synthetic aperture radar (SAR) signal excitation
• Wireless communication test and measurement equipment

Procurement Notes

Verify the specific suffix 'ACK' against the official Texas Instruments datasheet to confirm package type and temperature grade. Ensure compatibility with the DAC39RF10EVM development kit for initial validation. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent package damage during manufacturing.

Selection Notes

Select the DDS39RF10ACK over single-channel variants when dual-path I/Q modulation or simultaneous multi-carrier synthesis is required. Evaluate the 16-bit resolution against system dynamic range requirements, noting the specified DNL of 2.2 LSB and INL of 9 LSB. Consider the 256-pin FCBGA footprint constraints and thermal dissipation needs given the power consumption characteristics.

Part Context

This component belongs to the DDS39RF(S)10 series from Texas Instruments, designed for high-performance direct digital synthesis applications. It shares architectural similarities with the DDS39RFS10ACK but differs in channel configuration, offering two channels compared to the single-channel alternative. The series targets demanding RF environments requiring precise frequency control and wide bandwidth.

Replacement Considerations

The DDS39RFS10ACK serves as a functional substitute within the same family, differing primarily in having a single DAC channel instead of two. Verify pin-to-pin compatibility and software register configurations when migrating between these variants.
