DAC39RF10ACL

Digital To Analog Converters Overview

The DAC39RF10ACL is a dual-channel, 16-bit direct digital synthesizer and multi-Nyquist digital-to-analog converter manufactured by Texas Instruments. It features a maximum clock frequency of 10.24 GHz and supports sample rates up to 20.48 GSPS in single-edge mode or 10.24 GSPS per channel in dual-edge mode. The device provides an analog output bandwidth of 12 GHz with a resolution of 16 bits across two channels. It operates within a supply voltage range of 1.71 V to 1.89 V for analog sections and 0.95 V to 1.05 V for digital logic. The component utilizes an FCBGA-256 package (17mm x 17mm) and includes four integrated digital up-converters with interpolation factors ranging from 1x to 256x.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'ACL' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure that the selected variant matches the required pinout and thermal characteristics for the target PCB layout. Cross-reference the part number with official distributor catalogs to validate availability and lead times prior to finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select the DAC39RF10ACL when a dual-channel architecture is required for applications such as I/Q signal generation or direct RF sampling. Compare performance metrics like spurious-free dynamic range and noise floor against the single-channel DAC39RFS10 variant if only one output path is needed. Consider the power consumption and thermal dissipation requirements associated with the 256-ball FCBGA package during system design.

Digital To Analog Converters Part Context

This component belongs to the DAC39RF10 family of high-speed data converters designed for demanding RF applications. It shares architectural similarities with the DDS39RF10 series but is distinguished by its specific interface capabilities and intended use cases in direct digital synthesis. The device complements other members of the family, such as the DAC39RF12, which offers higher sampling rates but may differ in channel configuration or interface standards.

Digital To Analog Converters Replacement Considerations

The DAC39RFS10 serves as a single-channel alternative within the same family. For higher throughput requirements, the DAC39RF12 provides increased sampling rates. Verify compatibility with existing board layouts and software drivers before substituting these variants.
