DAC39RFS10ACK

Digital To Analog Converters Overview

The DAC39RFS10ACK is a single-channel, 16-bit Direct Digital Synthesizer (DDS) and digital-to-analog converter manufactured by Texas Instruments. It features a multi-Nyquist DAC core with a maximum clock frequency of 10.24 GHz and an analog output bandwidth of 12 GHz. The device supports up to 16 lanes via a JESD204C interface at speeds up to 12.8 Gbps per lane. It operates within a supply voltage range of 1.71 V to 1.89 V for analog supplies and -1.89 V to -1.71 V for negative supplies. The component is housed in a 256-ball FCBGA package measuring 17 mm x 17 mm with a 1 mm pitch.

Digital To Analog Converters Feature Summary

• Integrates four digital up-converters with interpolation factors ranging from 1x to 256x and 64-bit frequency resolution NCOs.
• Supports fast frequency hopping with phase coherence through a dedicated reconfiguration interface capable of 60ns updates.
• Includes internal AC coupling capacitors and SYSREF windowing for automatic timing calibration on the JESD204C interface.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'ACK' against the manufacturer's official documentation to confirm the package type and tape-and-reel or tray packaging details. Ensure that the ordering information matches the exact part number required for your design, as suffixes often dictate mechanical or shipping specifications rather than functional changes.

Digital To Analog Converters Selection Notes

Select the DAC39RFS10ACK when a single-channel high-speed RF signal generation path is required. Compare it against the dual-channel DAC39RF10 if two independent outputs are needed. Consider the radiation tolerance variants if the application involves space or high-radiation environments, as standard versions lack these qualifications.

Digital To Analog Converters Part Context

This component belongs to the DAC39RF10 family, which includes both dual-channel and single-channel variants. The single-channel version, DAC39RFS10, shares the same core architecture and performance metrics as its dual-channel counterpart but provides only one set of differential analog outputs. This makes it suitable for applications requiring high-performance direct RF sampling or complex baseband generation without the need for multiple channels.

Digital To Analog Converters Replacement Considerations

The dual-channel DAC39RF10 serves as a functional alternative if channel count is not a constraint. For higher speed requirements, the DAC39RF12 or DAC39RFS12 families offer 12/24 GSPS capabilities. Radiation-hardened versions such as the DAC39RFS10-SP or DAC39RFS10-SEP are available for specialized environments.
