DAC39RF12ACK

Digital To Analog Converters Overview

The DAC39RF12ACK is a dual-channel, 16-bit digital-to-analog converter (DAC) from Texas Instruments. It supports a maximum sample rate of 24 GSPS in single-channel mode and 12 GSPS per channel in dual-channel operation. 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 interface supporting 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 complex baseband digital up-converters for flexible signal generation.
• Supports fast frequency hopping with phase coherence via a dedicated reconfiguration interface.
• Includes internal AC coupling capacitors and deterministic latency compliance through JESD204C.

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 'ACK' against the manufacturer's current datasheet to confirm package type and material specifications. Ensure that the required development tools, such as the DAC39RF12EVM evaluation board, are available for design validation. Confirm that the supply chain source provides valid traceability documentation for this high-frequency component.

Digital To Analog Converters Selection Notes

Select the DAC39RF12ACK when a dual-channel architecture with 16-bit resolution is required for direct RF sampling applications. This part is suitable for designs needing multi-Nyquist zone operation and high-speed JESD204C connectivity. Consider the power dissipation characteristics and thermal management requirements associated with the 256-ball FCBGA package during system integration.

Digital To Analog Converters Part Context

This component belongs to the DAC39RF family, which includes variants like the DAC39RF10 and DDS39RFS12. While sharing similar architectural features, the DAC39RF12 offers higher sampling rates compared to the 10.24 GSPS devices. It differs from the single-channel RFS12 variant by providing two independent analog output channels for simultaneous signal processing.

Digital To Analog Converters Replacement Considerations

The DAC39RF10ACK serves as a lower-speed alternative within the same package footprint. For single-channel implementations, the DAC39RFS12ACK provides equivalent performance on one lane. Verify pin compatibility and register mapping before substituting these parts in existing designs.
