DAC39RF12ACL

Digital To Analog Converters Overview

The DAC39RF12ACL is a dual-channel, 16-bit digital-to-analog converter (DAC) from Texas Instruments. It supports maximum input data rates of 12 GSPS per channel in dual mode or 24 GSPS in single-channel direct RF sampling mode. The device features an analog output bandwidth of 12 GHz and integrates four digital up-converters with 64-bit NCO frequency resolution. 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

• Integrates four digital up-converters supporting complex baseband and direct RF sampling applications
• Supports fast frequency hopping with phase coherence via a dedicated reconfiguration interface
• Includes internal AC coupling capacitors and SYSREF windowing for simplified system synchronization

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 'ACL' against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Ensure that the supply voltage requirements and thermal management strategies align with the system design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this model when dual-channel operation with 16-bit resolution is required for direct RF sampling up to X-band frequencies. Consider the DAC39RFS12 variant if only a single channel is needed. Evaluate the JESD204C lane count requirements against the available SerDes interface capabilities of the upstream processor.

Digital To Analog Converters Part Context

This component belongs to the DAC39RF12 family, which includes dual-channel and single-channel variants. It serves as a high-performance solution for multi-Nyquist direct digital synthesis and arbitrary waveform generation. The device complements other members of the series by offering higher sample rates compared to the 10 GSPS class devices.

Digital To Analog Converters Replacement Considerations

The DAC39RFS12 is a single-channel alternative within the same family. For lower speed requirements, the DAC39RF10 series may be considered, though it offers reduced sample rates.
