DAC39RFS10ACL

Digital To Analog Converters Overview

The DAC39RFS10ACL is a single-channel, 16-bit direct digital synthesis (DDS) and arbitrary waveform generator (AWG) integrated circuit manufactured by Texas Instruments. It features a multi-Nyquist DAC core capable of operating at sampling rates up to 20.48 GSPS with an analog output bandwidth of 12 GHz. The device integrates four digital up-converters (DUCs) with interpolation factors ranging from 1x to 256x and 64-bit frequency resolution numerically controlled oscillators (NCOs). Data input is handled via a JESD204C compatible serial interface supporting up to 16 lanes at speeds up to 12.8 Gbps. The component is housed in a 256-ball flip-chip ball grid array (FCBGA) package measuring 17 mm by 17 mm.

Digital To Analog Converters Applications

• Satellite communications (SATCOM)
• Phased array antenna systems
• Synthetic aperture radar (SAR) exciter
• Wireless communications testers
• Arbitrary waveform generators (AWG)

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'ACL' against the manufacturer's official documentation to confirm package type, temperature range, and material compliance. Ensure that the ordering information matches the exact part number required for your design, as suffixes often denote variations in packaging or environmental ratings. Cross-reference the datasheet revision history for any updates regarding availability or recommended design changes before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a single-channel architecture is sufficient for the application, as opposed to the dual-channel DAC39RF10 variant. Evaluate the system requirements against the maximum input data rates, which vary based on bit depth and channel configuration. Consider the power supply constraints, as the device requires separate analog, digital, and clock supplies. Verify that the PCB layout can accommodate the 256-ball FCBGA package and meets the thermal dissipation requirements specified in the datasheet.

Digital To Analog Converters Part Context

The DAC39RFS10 belongs to the DAC39RF family of high-performance radio frequency digital-to-analog converters. This family includes both single-channel ('RFS10) and dual-channel ('RF10) variants, as well as radiation-tolerant versions for space applications. The 'RFS10 specifically targets applications requiring a single high-speed output path with advanced digital signal processing capabilities integrated directly on the silicon die.

Digital To Analog Converters Replacement Considerations

The DAC39RF10 serves as the dual-channel counterpart within the same family. For radiation-hardened requirements, consider the DAC39RFS10-SP or DAC39RFS10-SEP variants. Higher performance options include the DAC39RFS12 series, which offers increased sampling rates.
