DAC39RFS12ACL

Digital To Analog Converters Overview

The DAC39RFS12ACL is a single-channel, 16-bit multi-Nyquist digital-to-analog converter (DAC) from Texas Instruments. It supports a maximum input data rate of 24 GSPS in single-channel mode and features a 12 GHz analog output bandwidth. The device integrates four digital up-converters with 64-bit NCO resolution and a fast reconfiguration interface for phase-coherent frequency hopping. It utilizes a JESD204C compatible serial interface with up to 16 lanes at 12.8 Gbps. The component operates within a temperature range of -40°C to +85°C and is housed in a 256-ball FCBGA package measuring 17mm x 17mm.

Digital To Analog Converters Feature Summary

• Features a JESD204C compliant SerDes interface with internal AC coupling capacitors
• Includes SYSREF windowing for automatic timing calibration and deterministic latency

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 ordering suffix against the manufacturer's current documentation to ensure correct package variant and quality grade. Confirm that the required supply voltages and thermal management solutions align with the device's absolute maximum ratings and recommended operating conditions before finalizing procurement specifications.

Digital To Analog Converters Selection Notes

Select this single-channel variant when only one high-speed RF output path is required, as opposed to the dual-channel DAC39RF12. Ensure the system design accommodates the 24 GSPS maximum input data rate capability. Verify compatibility with the host processor's JESD204C lane count and clock distribution requirements for proper synchronization.

Digital To Analog Converters Part Context

This component belongs to the DAC39RF12/RFS12 family of high-performance multi-Nyquist DACs. It shares core architecture with the dual-channel DAC39RF12 but provides a single-channel configuration optimized for specific RF signal generation tasks. The family supports direct RF sampling through C-band and into X-band frequencies.

Digital To Analog Converters Replacement Considerations

The dual-channel DAC39RF12 serves as a functional alternative if two independent channels are needed. For lower speed requirements, the DAC39RF10 or DDS39RF12 families offer comparable architectures with different maximum sample rates.
